You can freeze any meat instead of buying it every week. Wrap the meat with aluminum foil and put it in a zipper bag for the raw meat. Then, place the meat in the refrigerator as soon as possible. You also have to wrap it with aluminum foil and put it on an air-tight box for the cooked meat. But you have to pour some gravy in the box to prevent drying out. You can store the cooked meat for at least three to four weeks.
