Dice the onion and red bell pepper.
In a deep skillet over medium-high heat, add a splash of oil, the diced onion, and the ground beef.
Cook, breaking the beef apart, until no longer pink, about 8 minutes.
Add the garlic powder, paprika, salt, pepper, pasta sauce, dry pasta, beef broth, and water. Stir well.
Cover and simmer on medium-low heat for 12 minutes, until the pasta is tender.
Remove the lid and stir in the blended cottage cheese and shredded cheddar cheese.
Cook for another 3 to 5 minutes until creamy, then remove from heat. Leave a little liquid, since the pasta will keep absorbing it.
Serve immediately.
