Slow Cooker Bow Tie Pasta Casserole

1 lb. ground beef

1 clove garlic

1 medium onion, chopped

2 (8oz.) cans tomato sauce

1 (14 oz.) can stewed tomatoes

1 tsp. Italian Seasoning

1 tsp. Oregano powder

Salt and pepper to taste

1 pkg frozen chopped spinach, thawed(I use less-I'm not a huge spinach person)

1 (16 pz. ) pkg bow tie pasta, cooked according to package directions

1/2 cup shredded parmesan cheese

2 cups shredded mozzarella cheese

Brown beef with garlic and onion. Drain. Place in slow cooker. Add tomato sauce, stewed tomatoes, seasonings. Cover and cook on low 7-8 hours. Last half hour, turn on high, add cooked pasta, cheeses, and spinach. Serves 6 or more-it makes a lot!
