2 1/2 c. baked ham, cubed
2 hard-cooked eggs
4 oz. American cheese, cubed
1 tbsp. minced onion
Mayonnaise

Mix cubed ham, chopped eggs, cheese and onion. Add just enough mayonnaise to moisten mixture, salt and pepper to taste. Place mixture on hamburger buns. Wrap in foil. Bake at 350 degrees for 30 minutes. Great way to use leftover ham.
