Prepare the Vegetables: Start by heating 1 tablespoon of olive oil in a large skillet over medium heat. Once the oil is shimmering, add the sliced onion and bell pepper. Sauté for about 5-7 minutes until the vegetables are softened and show a golden hue from caramelization. Season them with garlic powder, salt, and freshly ground black pepper. Once done, remove the vegetables from the skillet and set them aside on a plate.
Cook the Steak: In the same skillet, add the remaining tablespoon of olive oil. Increase the heat to medium-high, letting the oil heat until it shimmers. Add the thinly sliced sirloin steak in a single, even layer, and season with salt and pepper. Cook for about 3-4 minutes, stirring occasionally, until the steak is well-browned and cooked through.
Combine the Mixtures: Once the steak is cooked, return the sautéed bell pepper and onion to the skillet. Gently mix everything together, allowing the flavors to meld for an additional minute on low heat.
Assemble the Sliders: Preheat your oven to 350°F (175°C). Carefully slice the slider rolls in half horizontally and lay the bottom halves on a baking sheet. Spread a thin layer of mayonnaise on each bottom half, then generously layer the cheesesteak mixture on top. Place a single slice of provolone cheese over each portion of the cheesesteak mixture.
Bake: Cover the sliders by placing the top halves of the rolls on top. Slide the baking sheet into the preheated oven and bake for 10-12 minutes, or until the cheese is beautifully melted and the rolls are golden brown.
Optional Hot Sauce: For those who enjoy a little extra spice, drizzle hot sauce over the sliders just before serving to give them an exciting kick.
Notes
Serve with additional hot sauce on the side for dipping.
