Roast Beef Mushroom & Swiss Sliders
To make the Roast Beef Mushroom Swiss Sliders you’ll need the following ingredients:
- 1 small onion, diced
- 2 cups fresh mushrooms, sliced
- 2 cloves of garlic, minced
- 1-pound roast beef (I got mine from the deli)
- 1 package Seeds of Change Mushroom Simmer Sauce
- 2 tablespoons butter
- 4-6 slices of swiss cheese
- 1 package rolls
- 1/2 teaspoon onion powder
- 1/4 teaspoon garlic salt
- 2 tablespoons butter
- 1 teaspoon Worcestershire sauce
Follow the directions below to make these yummy sliders:
- Preheat oven to 350 degrees.
- Prepare baking pan by spraying with cooking spray.
- In a large saucepan combine onion, mushrooms, garlic, and butter. Sauté until onions and mushrooms are soft.
- Slice roast beef into strips. Add roast beef and Seeds of Change Mushroom Simmer Sauce to sautéed mushrooms and onions. Simmer for 10 minutes.
- Remove rolls from the package, but do not pull them apart. Cut them horizontally through the middle, so you have 2 slices – 1 with all the tops and the other with all the bottoms of the rolls.
- Place the bottom of the rolls in your baking pan and layer the roast beef, mushrooms, and swiss cheese.
- Put the tops of the rolls on top of the roast beef, mushroom and cheese layers.
- Melt 2 tablespoons butter, add Worcestershire sauce, garlic salt, and onion powder. Using a pastry brush lightly coat the top of the rolls.
- Cover with aluminum foil and place in the oven for 15 minutes.
- Remove from the oven and serve immediately.
