Not that I would even think of doing this, but here is what I just read...

"I wasn't able to follow this recipe, since I didn't have the soup and onion mix. But I wanted to add a tip that makes cooking in a crockpot SO much easier. Line the crockpot with a Reynold's oven cooking bag, Turkey size, or smaller depending on the size of your crockpot. Cooking time is the same. Then the best part, clean up. Just remove the ingredients, lift out the bag, and your done! The crockpot remains clean."
