Slow-Cooker Lasagna

I know this sounds a little crazy but it is super yummy and so easy, so give it a try.

1 jar (25-26 oz) marinara sauce
1 can diced tomatoes (14 1/2 oz)
1 package oven ready (no boil) lasagna noodles
1 container (15 oz) ricotta cheese
2 C. shredded mozzarella cheese
1 package (10 oz) frozen spinach
8 oz Italian sausage or hamburger

In bowl combine marinara sauce and tomatoes with their juice. Spoon 1 cup tomato sauce mixture into bottom of crockpot. Arrange noodles on top of sauce overlapping and breaking to cover as much area as possible. Spoon about 3/4 cup sauce over noodles, then top with 1/3 meat, ricotta, mozzarella, and spinach in layers. Repeat layers 2 more times. Top with noodles and remaining sauce and mozzarella cheese. Cover crock pot with lid and cook on high for 1 1/2 to 1 3/4 hours or on low for 2 1/2 to 3 hours or until noodles are tender.

*I seasoned the ricotta cheese to add some more flavor.
