One of my favorite things is planning our menu. It is fun because I plan our leftovers. They are either used in a meal the same week or I can /freeze so I can use it up during the next year.
When I bake a ham for "Feast" we have a leftover mean, then ham and bean soup and I have enough for 2 meals during the week and still can put up 5-6 jars for my pantry.
Baking a chicken gives us a "Feast" meal, a leftover meal, Chicken and Dumplings or noodles, and still I can put up 3-4 jars of chicken soup for use during the next year.
A standard Pot Roast meal can be used later for Hot Beef Sandwiches, Beef Stew, and Chili to can.
When you plan your menu with the idea of using leftovers you end up saving money in the long run. Even if all you do is turn it into lunch meat you will save money.
