If you can't find pre-shaved steak, freeze a ribeye or sirloin 15 minutes and slice it as thin as you can.
Cook sliced onion, pepper, and mushrooms in 1 tbsp oil in a large skillet over medium-high heat, 6-8 minutes until soft; set aside.
Add the remaining oil and the steak, season with salt and pepper, and cook 2-3 minutes, chopping with a spatula, until just browned.
Return the veggies, divide into 4 piles, and lay 2 provolone slices over each. Cover 1 minute to melt.
Toast the buttered rolls under the broiler for 1 minute, then scoop a cheesy pile into each. Keep veggies on the side for picky eaters.
