8 oz spaghetti
2 cups shredded sharp cheddar cheese
1 cup fresh bell peppers (chopped)
1 can (10.5 oz) cream of chicken soup
1 tsp paprika
1/2 tsp cayenne pepper

1/4 cup green onions (sliced)

Directions

Preheat your oven to 350°F (175°C). Grease a large casserole dish.
Cook the chicken in a large pot over medium heat for about 6-7 minutes per side until golden and cooked through.
Boil salted water and cook spaghetti until al dente (8-10 minutes). Drain and set aside.
In a bowl, mix shredded chicken, cooked spaghetti, cream of chicken soup, bell peppers, spices, and half of the cheddar cheese until well combined.

Let it rest for 5 minutes before garnishing with chopped green onions and serving.
