These are so simple it's silly, but my husband loves them so much I thought I'd post this. I like them, too! I've tried making these a few different ways, but I believe good old processed American cheese singles works the best for this - it's clean and easy to measure and roll up, and it melts perfectly during the allotted baking time. You can skip the cooking spray and foil if you want and just bake these directly on the baking sheet, but I like to do it this way because it makes clean up easier, and any leftovers can be stored and reheated right in the foil.
