Leftover Pot Roast Patty Melts
Beef
Sandwiches
2-3 cup leftover shredded pot roast
8 slices sturdy bread
3 tablespoons butter, plus more for the bread
2 medium onions, thinly sliced
Salt and pepper to taste
4 slices Swiss cheese
Sauce
½ cup mayonnaise
3 tablespoons steak sauce
⅛ teaspoon pepper
Re-heat the pot roast in the microwave. Butter one side of all 8 slices of bread.
Melt 3 tablespoons of butter in a large skillet. Add onions and cook over medium heat, stirring frequently, until onions are soft and golden brown.
Season with salt and pepper and remove from heat.
Combine the sauce ingredients in a medium bowl.
Heat a griddle over medium-high heat. Spread a layer of the sauce on the unbuttered side of 4 slices of bread. Top with a piece of Swiss cheese.
Top each with about ½ cup of pot roast, a generous portion of onions. Top with the remaining slice of bread, buttered side out.
Grill, flipping once, until both sides are browned and crispy.
Serve patty melts with the remaining sauce, for dipping.
