Turkey Sausage Pasta Bake

I got the recipe from Savvy Suzie, and thought it sounded good.

Sausage and Penne Bake
Ingredients:
1 pound box whole wheat penne pasta
1 pound Italian turkey sausage (hot or sweet - or use ground beef, turkey, or pork sausage!)
2 bell peppers, diced
1 small onion, diced
2 Tbsp minced garlic
1 (14 oz) jar tomato sauce
1 1/2 - 2 cups shredded mozzarella

Directions:- Preheat oven to 350 degrees- Cook pasta according to package directions, removing from heat while still slightly firm (about 8-10 minutes). Drain and set aside.- While pasta is boiling, crumble sausage into a skillet and brown over medium-high heat. After about 3 minutes, add peppers, onion and garlic, and brown for an additional 4-5 minutes. Stir in the tomato sauce and cook for an additional 3-4 minutes until heated.- Remove from heat, stir in penne and half the mozzarella. Transfer to a casserole dish. Sprinkle remaining mozzarella on top.- Bake for 20 minutes in the preheated oven, or until cheese is slightly browned and melted.
