Heat the olive oil in a large skillet over medium heat.
Add the sliced onions and bell peppers, and sauté until they are soft and slightly caramelized, about 5-7 minutes.
Push the vegetables to one side of the skillet, then add the thinly sliced ribeye steak to the other side. Season with garlic powder, salt, and pepper. Cook for about 3-4 minutes, stirring occasionally, until the steak is browned and cooked through.
Once the meat is cooked, mix it with the vegetables in the skillet and remove from heat.
Lay out the lettuce leaves and place 2 slices of provolone cheese on each leaf.
Spoon the steak and vegetable mixture evenly over the cheese in each lettuce leaf.
Starting from one end, carefully roll the lettuce leaf tightly around the filling to create a roll-up.
Repeat for all lettuce leaves.
To serve, you can secure the rolls with a toothpick, if desired, and drizzle with hot sauce for a spicy kick, if using.
Notes
Secure with a toothpick for easier serving. Optional hot sauce can add a spicy kick.
