That leftover Prime Rib or beef roast makes the best Italian Hot Beef Sandwich. You may be making more roast beef just so you can make these sandwiches.
– prime rib thinly sliced – onion sliced – green pepper sliced – mushrooms sliced – cheese: mozzarella, swiss, havarti or any melting cheese
Preheat the oven to the broil setting. Drizzle a skillet with extra virgin olive oil and heat on medium-high when hot add green peppers, onion, and mushrooms. Cook until just al dente.
