This is super easy, especially if you can have regular jarred marinara sauce. I can't because of an onion and garlic allergy. So I make my own sauce.
Blend all ingredients for marinara sauce in blender.
Cook Ravioli according to package directions.
Pour ravioli into 9x13 glass pan. Pour marinara sauce on top and stir till covered.
Top ravioli with cottage cheese, parmesan cheese and shredded cheese.
Heat in oven until cheese is melted and sauce is bubbling.
