Ingredients

Instructions

  1. Step 1: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1/2 medium sliced yellow onion and 1/2 medium sliced green bell pepper, sauté for 5-6 minutes until softened and slightly caramelized.
  2. Step 2: Remove vegetables and add remaining 1 tbsp olive oil to the skillet. Increase heat to high and add 8 oz thinly sliced ribeye steak seasoned with 1/2 tsp salt, 1/4 tsp black pepper, and 1/4 tsp garlic powder. Sear for 2-3 minutes until browned but still tender.
  3. Step 3: Return the sautéed onions and peppers to the skillet with the steak, stir for 1 minute to combine and heat through.
  4. Step 4: Slice 1 hoagie roll lengthwise without cutting through, layer the steak mixture evenly inside, then top with 3 slices of provolone cheese.
  5. Step 5: Place the sandwich under a broiler or in a toaster oven for 2-3 minutes until the cheese melts and the bread is toasted. Serve hot.
