We love to keep our men happy with this appetizer. It makes 30 sandwiches.
1 cup ground ham
3 tbsp mayonnaise
20 slices raisin bread
½ cup grated Swiss cheese 
½ tsp prepared mustard
¼ cup softened butter
Mix ham, cheese, mayonnaise and mustard together. Spread raisin bread slices with softened butter. Spread half the slices with the ham mixture and top with remaining slices of bread. Trim crust. Cut into three “fingers.” Cover with plastic wrap or aluminum foil. Chill. This recipe is good for lunch boxes, picnics and parties.
