My mom would make these Cuban burgers when we would visit her in Florida. They are a take on the real Cuban sandwich. My kids love them. My boys could eat two of these monsters in one sitting. —Marina Castle Kelley, Canyon Country, California
Prepare grill for medium heat. Place a large cast-iron skillet on grill grates.
In a large bowl, combine beef, pork, lemon juice, 1/2 teaspoon garlic salt and 1/4 teaspoon pepper, mixing lightly but thoroughly. Shape into four 1/2-in.-thick patties. Grill burgers, covered, over medium heat until a thermometer reads 160°, 5-7 minutes on each side.
Combine mayonnaise, mustard, remaining 1/2 teaspoon garlic salt and 1/4 teaspoon pepper; spread over cut sides of buns. Place burgers on bun bottoms; top with Swiss cheese, ham, pickles and bun tops. Using oven mitts, carefully place preheated skillet on sandwiches. Grill sandwiches, covered, until buns are browned and cheese is melted, 5-8 minutes.
