What's your favorite idea for leftover roast beef? I ran across this idea in a vintage cookbook and thought you would enjoy it. I'm thinking a little minced onion would be a great addition.
Take the remains of cold roasted beef, and chop very fine; put it into a bowl; to each half pint of meat, add a half teaspoonful of salt, a tablespoonful of tomato catsup, a teaspoonful of Worcestershire sauce and a teaspoonful of melted butter; work this together. Cut the crust from the ends of a loaf of whole wheat bread; butter lightlyand slice; so continue until you have the desired number of slices; spread the slices with a layer of the seasoned meat; put two slices together, and cut into desired shapes.
