Step 1

Preheat oven to 375.

Cook pasta according to package directions. Leave it "al dente" - just cooked/still a little chewy.

In a large pan, saute onion and bell peppers in a little oil or cooking spray over high heat for a few minutes, until onions are translucent.

Step 4

Add baby spinach and frozen peas and reduce heat to medium. Cover, stirring occasionally, until peas are no longer frozen and spinach is fully wilted.

Step 5

In a large bowl, mix together cooked pasta, the sauteed veggie mixture, and all other ingredients.

Step 6

Pour mixture into a casserole dish.

Step 7

Bake 40 minutes. Enjoy!
