This is great way to beat the heat and use up leftovers! My family (both sides) have made this staple for generations. I can still see my Grandma using the crank meat grinder to make hers. Mom always made hers with the grinding attachment on her mixer and I've done the same (have also made it with the food processor). While we used to make this when we had left over roast beef, I have used lesser cuts of roasts to make this spread which is a great inexpensive way to extend the food budget. We like to serve this on fresh soft bread with lettuce and tomato slices. *Note* Deli Roast Beef is NOT recommended for this recipe.
