I found an easy slow cooker recipe that was as quick as it was tasty, and I was told it tasted better than Chef Boyardee.
1 25 oz bag of frozen ravioli (I used cheese)
1 jar of pasta sauce of your choice
1 cup (or amount of your choosing) mozzarella cheese
1. Place a small amount of sauce in the bottom of the slow cooker. Top with bag of ravioli, and pour the remaining sauce over the top. Stir to coat evenly.
2. Cook for around 1 1/2 hours (the original recipe said 2 1/2 hours, but my sauce began to burn after about 2 hours). After 1 1/2 hours, top with cheese and cook until cheese is melted and bubbly.
This was a big hit with in my house!
