Step 1

Preheat the oven to 350 degrees F. Split the bread lengthwise and spread the bottom of the loaf with mayo. Make an even layer of the pork, then add the ham, pickles, and cheese. Top with the other piece of bread and press lightly but firmly.

Step 2

Wrap the sandwich(es) securely in foil and lay between 2 baking sheets. Set on the oven rack and weight the top sheet with a heavy ovenproof skillet. Bake until warmed through and the cheese has softened, about 30 minutes.

Step 3

Serve warm, cut into manageable pieces.
