Heat 1 tablespoon olive oil in a large non-stick skillet and add the sliced peppers and onions to the pan. Season with salt, pepper, and a pinch of garlic powder. Cook for 5-6 minutes until soft and tender. Remove the veggies from the skillet and set them aside.
Slice the rolls in half and place them on a baking sheet. Place 2 slices of Provolone cheese on each bun and cook in the oven for 5-6 minutes until the cheese is melted and gooey and the buns are toasted.
Cook the shaved beef steak in 2 batches over medium-high heat so that it can caramelize and get crispy.
Add the 2nd tablespoon of olive oil to the pan as needed for cooking the 2nd batch of beef. Once all the beef is cooked, add the remaining beef, peppers and onions and season with steak seasoning, garlic powder, salt and pepper. Stir to combine.
Place 1/3 cup of shaved beef steak on each bun and serve hot.
