Cut crusts off bread slices and then cut all slices in half.
Cut all slices of bacon into thirds
Spread all of the crustless bread halves with cream of mushroom soup. Take 1/3 of slice of bacon and lay the bread slice on top of it, and roll up. Secure with a toothpick. Place on cookie sheet (that has lip on it) Continue until all bread is used up.
You can freeze them at this point or bake in the oven on 425 degrees until browned--approximately 20 minutes (turn 1/2 way through baking). (Do not broil as the bread will burn before the bacon is sufficiently cooked).
Note: If you freeze them, you don't have to defrost them before cooking.
