Cheesesteak Subs

adapted from a recipe at Mel's Kitchen Cafe:

Makes 3 stuffed subs, or 4 normal subs (I personally go for the stuffed subs, otherwise the bread seems to take over).

2 tablespoons butter
1 onion, halved and sliced into thin half moons
1/2 cup sliced mushrooms
2 garlic cloves, finely minced
1/4 teaspoon dried oregano
2 tablespoons A-1 steak sauce
1 pound deli roast beef, cut into 2-inch strips
Salt and pepper
4 (6-inch) sub rolls, split partially open lengthwise
8 slices provolone cheese

Preheat the broiler in your oven and adjust a rack to the upper-middle position. Meanwhile, in a large skillet, melt the butter, Add the onion and mushrooms and cook until softened and golden, about 8 minutes. Stir in the garlic and oregano and cook for a minute, until it smells fragrant. Add the A-1 sauce and the beef, stirring well to coat the beef with the sauce and onion/butter mixture. Cook until the meat is heated through, about 2 minutes. Season with salt and pepper.

Place the sliced rolls on a rimmed baking sheet. Divide the beef mixture among the rolls. Top with the cheese and broil until the cheese is melted, about 2 minutes (don’t even take your hand off the oven door handle – stand right there so they don’t burn!). Serve immediately.
