1 package (12 count) Hawaiian sweet rolls or slider buns
1 lb deli roast beef, thinly sliced
1/2 lb Provolone cheese slices
1 large green bell pepper, thinly sliced
1 medium yellow onion, thinly sliced
2 tablespoons olive oil
4 tablespoons unsalted butter, melted
1 teaspoon garlic powder
1 teaspoon Worcestershire sauce
1/2 teaspoon dried parsley
Salt and black pepper to taste
Instructions
Sauté the Vegetables: In a large skillet, heat the olive oil over medium heat. Add the sliced onions and green bell peppers. Sauté for about 8 to 10 minutes until they are soft and slightly caramelized. Season with a pinch of salt and pepper, then remove from heat.
Prepare the Slider Rolls: Preheat your oven to 350°F (175°C). Without pulling the individual rolls apart, slice the entire slab of slider rolls in half horizontally. Place the bottom half of the rolls into a greased 9×13 inch baking dish.
Layer the Beef and Cheese: Layer half of the Provolone cheese slices over the bottom rolls. Top the cheese with the thinly sliced roast beef, spreading it evenly across the surface. Add the sautéed peppers and onions over the meat, and then layer the remaining cheese slices on top of the vegetables.
Prepare the Garlic Butter Glaze: Place the top half of the rolls over the cheese layer. In a small bowl, whisk together the melted butter, garlic powder, Worcestershire sauce, and dried parsley. Use a pastry brush to coat the tops of the rolls generously with the butter mixture.
Bake to Perfection: Cover the baking dish with aluminum foil. Bake for 10 minutes, then remove the foil and bake for an additional 10 minutes. The cheese should be completely melted and the tops of the rolls should be golden brown and slightly crisp. Serve warm.
