Cook the quinoa according to package instructions. Set aside to cool slightly.
Cook the chicken — air fry tossed in chili lime seasoning, or grill or pan-fry — then dice into bite-sized pieces.
Rinse and drain the black beans and corn.
Optional but recommended: sauté the corn in a drizzle of oil over medium-high heat until lightly charred.
Whisk together all dressing ingredients: olive oil, lime juice, maple syrup, chili powder, salt, and pepper.
In a large bowl, combine the quinoa, black beans, corn, red bell pepper, red onion, and jalapeño.
Add the diced chicken and toss everything well with the dressing until fully coated.
Store in the fridge for up to 4 days. Serve cold or at room temperature.
