This was Germany’s 70/80th party food. I remember when my older sisters had house parties, and these easy toast with ham, pineapple and cheese open faced sandwiches were a hit.
These days I still make it occasionally for an easy evening snack or Brotzeit. My daughter introduced her American husband to it, and he loved these exotic open faced sandwiches.
4 slices of buttered toast, I do both sides. Place cooked ham on top, the pineapple slices, cheddar, or some other melting cheese. Bake in preheated oven on a baking sheet at 350 F for 10 to 15 minutes. Right before the cheese turns brown remove from oven.
