Ingredients

  • 1 medium onion, thinly sliced
  • 1 medium jalapeno, seeded and thinly sliced
  • 1/2 red bell pepper, thinly sliced
  • 1/4 cup coarsely chopped cilantro
  • 3 tablespoons olive oil
  • 2 tablespoons fresh lemon juice
  • 1/4 teaspoon finely grated lemon zest
  • Salt and freshly ground pepper
  • 4 kaiser or hard rolls, trimmed and halved
  • Vegetable oil
  • 10 ounces smoked mozzarella, cut into 16 thin slices
  • 1 pound roast pork, cut into 16 slices

Method

  • In a bowl, combine the onion, jalapeno, bell pepper, cilantro, olive oil, lemon juice and lemon zest and season with salt and pepper.
  • Spread 2 tablespoons of the fresh onion relish on each kaiser roll half.
  • Set a large skillet over moderate heat and coat with a thin layer of vegetable oil.
  • Place 2 roll halves in the skillet, relish side up, and top each with 2 mozzarella slices, 4 pork slices and 2 more mozzarella slices.
  • Reduce the heat to low and cover each sandwich with another roll half, relish side down.
  • Weight down the sandwiches with a medium skillet and cook until the bottoms are toasted and the bottom layer of cheese has melted, about 4 minutes.
  • Turn the sandwiches, add a little more oil to the skillet and brown the second sides, about 4 minutes.
  • Transfer to plates and repeat with the remaining ingredients to make 2 more sandwiches.
