Prepare rigatoni pasta according to package directions, cooking to al dente (or just slightly chewy.) Chop onion and pepper and put aside.
In large frying pan, add 1 tbsp. oil and butter. Add sliced sausage and cook until browned.
Remove and drain all oil by letting them sit on a paper towel. Add the 1 tbsp butter and oil to the same pan and saute the chopped onion, pepper and garlic.
Once the onions are a translucent color, remove from heat and drain on same paper towel. Place the cooked rigatoni in a casserole dish, then add the Alfredo sauce, sausage, onion and peppers and thoroughly coat.
If the cheese is not already shredded, do so and mix in. Once everything is mixed, cover the top with breadcrumbs.
Bake the mixture at 350-375 degrees until the cheese is melted and the bread crumbs have browned (about 20-30 minutes).
Delicious!!
