Bacon in a Toaster. Bacon would be prefried, then hermetically sealed in this design for a future aluminum package. One way to heat it for eating would be to drop it in the toaster; another, put in oven or broiler. A major advantage is the elimination of utensils for cooking. Package is opened by turning back the edges. Leftovers are easily preserved by refolding the pouch.
