Ingredients

1. 3/4 cup cornichons, chopped, plus 1/2 tablespoon cornichon pickling liquid
2. 1/4 cup sliced pickled jalapeños, chopped
3. 2 tablespoons drained capers, chopped
4. 3 tablespoons Dijon mustard
5. 4 large French bread rolls, split, or 1 large baguette, cut into 4 pieces
6. 3 tablespoons extra-virgin olive oil
7. 4 cups shredded Gruyère cheese (10 ounces)
8. 2 pounds roasted pork, preferably shoulder, sliced 1/4 inch thick
9. Kosher salt and freshly ground pepper
10. 1/4 pound thinly sliced prosciutto

1. Preheat the oven to 375°. In a bowl, mix the cornichons and their pickling liquid with the jalapeños, capers and mustard.
2. Brush the outside of the rolls with the oil and place each on a 12-inch piece of foil, cut side up. Sprinkle 1/2 cup of Gruyère over the bottom half of each roll. Top with the sliced pork. Spread 1/4 cup of the cornichon mixture over the pork and season with salt and pepper. Top with the prosciutto and the remaining Gruyère. Close the sandwiches; tightly roll them up in foil. Bake for 20 minutes, until the cheese is melted and the rolls are crisp. Slice the sandwiches in half on the bias and serve.
