Mediterranean Quinoa Salad (Easy Summer Side Dish)

This Mediterranean quinoa salad is the kind of side dish that makes the whole table look like you put in a lot more effort than you actually did. Peppery arugula, fluffy quinoa, juicy cherry tomatoes, crisp cucumber, briny kalamata olives, and salty crumbled feta — all tossed together in a simple red wine vinegar and olive oil dressing. It’s fresh, it’s bold, and it’s ready in about 15 minutes. This is the salad you bring to every summer cookout, serve alongside grilled chicken or beef, or pack for lunch all week long.

I’ve been making this Mediterranean quinoa salad on repeat all summer and I genuinely can’t get enough of it. The combination of peppery arugula with the earthy quinoa and those salty Mediterranean toppings is just perfect. And the dressing couldn’t be simpler — just red wine vinegar, olive oil, salt, pepper, and dried oregano. That’s it. No blender required.

Why You’ll Love This Mediterranean Quinoa Salad

• Ready in 15 minutes. The quinoa takes about 12 minutes to cook, and while it does its thing you chop all the vegetables. Everything comes together fast.
• Perfect for summer entertaining. This salad is stunning on a table. The colours — deep green arugula, red cherry tomatoes, white feta, purple olives — are beautiful.
• Great as a side or a main. Pair it with grilled chicken or steak for a full dinner, or serve it as a standalone salad for a lighter meal. It works both ways.
• Meal prep friendly. Make a big batch at the start of the week and enjoy it for lunch for days. The quinoa actually gets better as it soaks up the dressing.
• Endlessly customizable. Add grilled chicken, roasted red peppers, sun-dried tomatoes, or chickpeas — this salad is a great base for whatever you have on hand.
• No heavy dressing. Just good olive oil and red wine vinegar. Light, bright, and Mediterranean-forward.

Ingredients for This Mediterranean Quinoa Salad

Here’s everything that goes into this salad and why each ingredient matters:

• Arugula (4 cups, roughly chopped) — The peppery, slightly bitter base of the salad that pairs beautifully with the salty Mediterranean toppings. Chop it roughly so it’s easier to eat.
• Cherry tomatoes (1 pint, diced) — Adds sweetness and juiciness that balances the bitter arugula and salty feta. Dice them small so they distribute evenly through the salad.
• Mini cucumbers (2, diced) — Crisp and refreshing with a mild flavour that adds great texture. Mini cucumbers are less watery than regular cucumbers.
• Red onion (2 tbsp, diced) — Just a small amount for sharpness and a little punch. If you find raw red onion too strong, soak the diced pieces in cold water for 5 minutes to mellow the flavour.
• Kalamata olives (¼ cup, diced) — Deep, briny, and intensely flavourful. These are non-negotiable in a Mediterranean salad — they add a richness that you just can’t replicate.
• Feta cheese (¼ cup crumbled, or more) — Salty, creamy, and the perfect finishing touch. Use more if you love feta — there’s no such thing as too much in this salad.
• Red wine vinegar — Adds bright acidity that wakes everything up. Start with about 2 tablespoons and adjust to taste.
• Olive oil — Use a good quality extra virgin olive oil. About 3 tablespoons.
• Salt, pepper, and dried oregano — The simple seasoning that ties the whole Mediterranean flavour profile together. Dried oregano is key — don’t skip it.

How to Make This Mediterranean Arugula Quinoa Salad

This salad comes together in just a few easy steps:

1. Cook the quinoa. Rinse your quinoa, then cook according to package directions. Fluff with a fork and let it cool slightly before adding to the salad.
2. Chop your vegetables. While the quinoa cooks, dice your cherry tomatoes, cucumbers, red onion, and kalamata olives. Roughly chop the arugula.
3. Make the dressing. Whisk together the red wine vinegar, olive oil, salt, pepper, and dried oregano. Taste and adjust seasoning.
4. Toss it all together. Add the cooked (slightly cooled) quinoa to a large bowl with the arugula and all the chopped vegetables. Pour the dressing over and toss well.
5. Top with feta and serve. Crumble the feta generously over the top, taste for seasoning, and serve.

Tips for the Best Mediterranean Arugula Quinoa Salad

• Let the quinoa cool before mixing. Hot quinoa will wilt your arugula. Let it cool for at least 5–10 minutes first.
• Dress it just before serving if you want the arugula to stay crisp. If you’re making it for meal prep, dress it and refrigerate — the quinoa soaks up the flavours beautifully overnight.
• Don’t be shy with the feta. The salt from the feta is part of what makes this salad so good. Taste as you go and add more if needed.
• Use good olive oil. A fruity, grassy extra virgin olive oil makes a noticeable difference in this simple dressing.
• Add protein to make it a full meal. Sliced grilled chicken, shrimp, or chickpeas turn this side dish into a satisfying main course.

How to Serve This Mediterranean Arugula Quinoa Salad

This salad is incredibly versatile:

• As a summer side dish — The perfect pairing for grilled chicken thighs, steak, lamb chops, or grilled salmon. The freshness cuts right through the richness of grilled meat.
• As a standalone lunch — Add grilled chicken or chickpeas on top for a complete, satisfying meal.
• For a crowd — This salad scales up beautifully. Double or triple the recipe for a summer cookout.
• For meal prep — Make a large batch on Sunday. It keeps well for 3–4 days and the flavours improve as the quinoa soaks up the dressing.

Frequently Asked Questions

Can I make this Mediterranean quinoa salad ahead of time?

Yes! The quinoa soaks up the dressing and gets even more flavourful the next day. If you want to keep the arugula crisp, store the dressing separately and toss just before serving. It keeps well in the fridge for 3–4 days.

What can I serve with this salad?

This is a perfect side dish for anything coming off the grill — chicken thighs, steak, lamb, salmon, or grilled halloumi for a vegetarian option. It also works beautifully as a standalone lunch with added protein.

Can I use baby spinach instead of arugula?

Yes, baby spinach works well as a substitute if you prefer a milder flavour. Arugula has a peppery bite that pairs beautifully with the Mediterranean ingredients, but spinach is a great swap.

Can I use pre-cooked or frozen quinoa?

Absolutely. Pre-cooked microwavable quinoa pouches work perfectly here and cut the prep time down to about 5 minutes. Just heat and cool slightly before adding to the salad.

How do I keep the red onion from being too sharp?

Soak the diced red onion in cold water for 5 minutes before adding it to the salad. This mellows the sharpness while keeping the onion crisp.

Can I add other vegetables or proteins?

Absolutely. Roasted red peppers, sun-dried tomatoes, artichoke hearts, chickpeas, grilled chicken, or shrimp all work beautifully here.
