Spicy Roast Beef and Capicola Sub Sandwich
- 1 tablespoon extra-virgin olive oil
- 12 ounces thinly sliced deli roast beef, cut into strips
- 6 ounces thinly sliced hot capicola ham, cut into strips
- 1 sweet onion, sliced 1/4 inch thick
- 1 red pepper, seeded and sliced into 1/2-inch-wide pieces
- 1 yellow pepper, seeded and sliced into 1/2-inch-wide pieces
- 2 tablespoons tomato paste
- 2 tablespoons brine from a jar of hot pickled cherry peppers, plus 3 peppers seeded and chopped
- Four 8-inch sub rolls, split and lightly toasted
- 4 ounces thinly sliced provolone
Preheat the oven to 200°C.
Heat 1 1/2 teaspoons of the olive oil in a large skillet over medium-high heat. Add the beef and capicola, and cook, stirring, until just beginning to crisp on the edges, about 3 minutes; transfer to a plate with a slotted spoon. Add the remaining 1 1/2 teaspoons olive oil, onions and bell peppers and cook, stirring, until crisp-tender, about 5 minutes.
Scoot the vegetables to the side of the pan. Add the tomato paste to the open space and toast, stirring for a minute, and then combine with the vegetables. Add the cherry pepper brine and 1/2 cup water, bring to a simmer and return the meat to the pan. Simmer just until the sauce coats the meat and vegetables, about 1 minute.
Divide the meat and vegetables among the rolls. Top with the cherry peppers and provolone. Bake on a baking sheet until the cheese is melted and bubbly, about 2 minutes.
