Coat the bottom of a crock pot with a small amount of the spaghetti sauce and turn on high heat

Mix together Ricotta cheese, half the bag of Mozzarella cheese, basil, salt and pepper, granulated garlic, and chopped garlic and cooled cooked spinach

Stuff the shells and place into crock pot, add the rest of the bag of cheese, and top with remaining jar of sauce!

I added more salt and pepper, granulated garlic, and basil and closed the lid! Cook for 4 hours on high!
