Mom Tip: We love to use our indoor grill (George Foreman) to gril burgers during the winter months – however I the mom am not to excited about the clean-up afterwards – The grease and grime are more then I want to deal with after dinner. Not any longer with this tip of using foil . Use a piece twice to size of your grill area then fold it in half and place it on the grill then use just like you did before grill your hamburgers and other items. . After you grill your burgers/cooked food simply remove the foil and you will discover a mess free grill.
