A Philly Favorite Gets Pumped for the Big Game
Preheat the oven to 250 F.
Heat a large, cast-iron skillet over medium-high heat. Add 3 tablespoons of the olive oil to the pan. Add the peppers and mushrooms and saute until slightly softened, about 3 minutes. Add the onion and saute until it's just the way you like it. Transfer the peppers, mushrooms and onion to an ovenproof platter and place it in the oven to keep warm.
Heat the remaining olive oil in the pan over medium-high heat. Add the oregano, salt and pepper to taste and saute quickly. As soon as the seasonings are hot, saute the steak for 5-6 minutes. Turn the steak and cook for another 5-6 minutes for medium-rare.
Remove the steak from the pan, place on a cutting board, and let it rest for 5 minutes. Thinly slice the steak. With tongs, divide the meat among the hoagie rolls and top with the onion mixture. Spoon some of the cheese sauce over the meat and vegetables, cover with the top of the roll, and serve.
Homemade Provolone Sauce:
Slow, gentle heat is the key to a smooth, creamy cheese sauce.
Half-fill the bottom of a double boiler with water and place over medium heat. Melt the butter in the top of the double boiler. Add the cheese and let if soften slowly, stirring.
Meanwhile, in a medium bowl, whisk together the egg yolks, flour and milk. When the cheese has melted, pour the egg mixture into the top of the double boiler and whisk until the sauce is warm and begins to thicken. Continue to cook over medium heat, whisking constantly. Add salt and pepper to taste. When the sauce is thick, turn the heat to low to keep it warm while you assemble the sandwiches. Cover and refrigerate any leftover sauce.
