Here's a childhood favorite from the 1950s; it's a really delicious and healthy sandwich filling!
If you have an old-fashioned meat grinder, set it up on your kitchen counter and feed it equal parts Carrots and raisins. Then add a hefty dollop of mayonnaise and mix it in. If you don't have a meat grinder, grate the Carrots with a hand grater and chop up the raisins with a knife. You can use a food processor, but it just won't taste the same.
