Crock-pot Ravioli Casserole

Ingredients

1 1/2 lbs. lean ground beef
1 onion, chopped
1 clove garlic, minced
1 (15 oz.) can tomato sauce
1 can stewed tomatoes
1 tsp. oregano
1 tsp. Italian seasoning
salt/pepper
10 oz. frozen spinach, thawed (I used fresh spinach)
16 oz. bowtie pasta, cooked
1/2 cup parmesan cheese, shredded
1 1/2 cup mozzarella, shredded

Instructions

Brown ground beef with onion and garlic. Put in crock-pot and add sauce, tomatoes, and seasonings. Cook for 6-7 hours on low.
Add the last 4 ingredients during the last 30 minutes of cooking and turn the crock-pot to high. I added the fresh spinach, pasta, parmesan, and 1 cup of the mozzarella and I mixed it all up really well. Then I added the last 1/2 cup of mozzarella to melt on the top.
