1. Prep the Veggies: Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the sliced onions and bell peppers, seasoning with salt and pepper. Cook until softened and slightly caramelized, about 8-10 minutes. Remove from the skillet and set aside.
2. Mix and Form Patties: In a bowl, mix the ground beef with garlic powder, Worcestershire sauce, salt, and pepper. Form into 4 patties.
3. Cook the Patties: In the same skillet, add another tablespoon of olive oil. Cook the patties on medium heat for about 5 minutes per side, or until they reach your desired doneness.
4. Melt the Cheese: A minute before the patties are done, top each with a mix of mozzarella and provolone cheese. Cover the skillet to help the cheese melt.
5. Assemble the Burgers: Toast the hamburger buns lightly, if desired. Place the cooked patties on the buns and top with the cooked onions and peppers.
