Cook the cavatappi pasta according to package instructions. Drain and set aside.

In a skillet, heat olive oil over medium heat. Add onion, garlic, and red bell pepper. Cook until softened. Add ground beef and cook until browned. Stir in chili powder, cumin, paprika, salt, and pepper. Add black beans, corn, and tomato sauce. Simmer for 5-7 minutes.

Add the cooked cavatappi pasta to the skillet with the beef mixture. Stir to combine and heat through.

Sprinkle cheddar cheese over the pasta and beef mixture. Transfer the skillet to the oven and broil until the cheese is melted and bubbly.

Garnish with chopped green onions before serving.
