1. In a large bowl combine water, meatballs, and spaghetti sauce.
2. Layer bottom of crockpot with 1/3 sauce/meatball mixture, then 1/3 dry noodles (break to fit), then 1/3 of ricotta cheese, then sprinkle some mozzarella cheese. Repeat this 2 more times. End with mozzarella on top.
3. Cook on low setting for 3 to 4 hours. This makes A LOT of lasagna! If desired you can half this recipe.
