Cuban sandwich

2 teaspoons margarine or butter
4 (8-inch) soft hero or club rolls (3 to 4 ounces each)
Prepared mustard
12 ounces sliced deli baked ham and/or roast turkey breast
16 slices kosher dill pickles or 8 sandwich slices
6 ounces sliced provolone and/or Swiss cheese
Mayonnaise

1. In nonstick 12-inch skillet, heat margarine over low heat. Meanwhile, assemble sandwiches: Split each roll horizontally in half. Lightly spread mustard on bottom halves of rolls (about 1 1/2 teaspoons per roll or to taste). Top each with one-fourth of ham, pickles, and cheese. Lightly spread mayonnaise on top halves of rolls (about 1 1/2 teaspoons per roll or to taste); place on top of sandwiches.
2. Increase heat to medium and arrange sandwiches in center of skillet. Place heavy skillet (preferably cast iron) on top of sandwiches and cook 4 to 5 minutes or until cheese melts and rolls are browned on both sides, turning sandwiches over once.
