My grandma would use absolutely every last bit of kitchen scraps. If she had prepared a roast for supper, several day later the roast, if any left would be ground into beef salad spread for a sandwich, ham would become ham salad for a sandwich and so on.
Grandma Houlihan lived in Spokane and I grew up on the west side, moving here when I was in first grade. When we would go visit Grandma she would always pack us a shoe box lunch for our road trip home on the train or by car.
This little box tied with string would contain homemade bun sandwiches piled with ground meat, pickles, mayo and onion. There would be homemade donuts or giant molasses cookies. Often the box would be opened before we even got to the freeway or settled in our seats on the train to begin our journey home..
If you've not ever tried using your leftover roast, ham or chicken for grinding into a sandwich-spread you are missing out. I just made extra pork tenderloin for supper yesterday just so I could make meat sammies.
Sometimes I finally dice with a knife or you can place the meat in a Cuisinart. Add Mayo, onion, and diced pickle sweet or dill this is all done to your personal taste.
Today I piled my ham salad on a romaine lettuce leaf. (Only because I'm saving my carb load for the fresh bread coming out of the oven at dinner).
Try it, you'll like it!
