Step 2 – Cook the vegetables
Heat butter or oil in a large skillet, then sauté the onions, peppers, mushrooms, and garlic until softened.
Step 3 – Cook the steak
Add the steak to the skillet, season it well, and cook until browned and cooked through.
Step 4 – Add the cheese
Return the vegetables to the skillet if you removed them earlier, then layer the provolone over the top and cover the pan until the cheese melts.
Step 5 – Serve hot
Scoop and serve immediately while the cheese is still gooey and the steak is juicy.
