This is a variety for cold meat sandwiches. Mom always fixed these before card club on Saturday nights.
Bologna, salami, ham, or any mixture of lunchmeat you prefer
American cheese
Swiss cheese
Onion
Miracle Whip
French bread
Slice French bread, spread with Miracle Whip, layer lunch meat and cheese. Wrap in foil and bake at 350° until cheese is melted. It takes longer than you think.
