Heat olive oil in a large skillet over medium-high heat.
Add sliced ribeye steak to the skillet and cook for about 3-4 minutes until browned.
Stir in sliced onion and bell pepper, cooking until they're softened, about 5 minutes.
Season with salt and pepper to taste during cooking.
Once vegetables are tender, reduce heat to low and sprinkle shredded provolone cheese over the mixture.
Cover the skillet for a couple of minutes to help the cheese melt thoroughly.
Serve the meat and vegetable mixture over a bed of cooked rice or quinoa.
Garnish with chopped scallions if desired and enjoy!
