Frozen Ravioli, pasta sauce and mozzarella cheese.
Here's what you need to do:
Take a bag (about 25 oz) frozen ravioli. Dump it in the crockpot.
Take a jar of pasta sauce. Repeat.
Cover and cook on high 2 1/2-3 hrs. 20 min before serving top with cheese. Cover and let the cheese melt.
I doubled the recipe using 1 bag of cheese ravioli and one bag of cheese and mushroom ravioli.
