When my sister was out visiting, she showed me the joys of tin foil. She was making a meatloaf. I guess at home she usually does it on a cookie sheet, but I insisted she cook it in a deep casserole pan because I thought a cookie sheet for meatloaf sounded weird. She obliged, but said that she usually puts tinfoil down. I did the same. At clean up time, I realized that tin foil could make my life a whole lot simpler in regards to the dishes.
Goodness, why didn't someone mention this sooner? Thanks to Marie for the simple tip!
