Baked Pasta with Sausage & Spinach - seriously delicious!! Can make ahead and freeze for later. Italian sausage, spaghetti sauce, diced tomatoes, cottage cheese, sour cream, spinach, spaghetti, parsley, garlic, monterey jack cheese, mozzarella cheese, french fried onions. Seriously THE BEST! Everyone cleaned their plate and went back for seconds! That never happens in our house. This is a keeper!!
