Ingredients
4 tablespoons oil or butter, divided
1 small onion, sliced into half-moons
1 cup sliced mushrooms
2 pounds steak, thinly sliced (such as ribeye)
8 slices provolone cheese
8 slider buns
cheese sauce, optional
Directions
1
Gather the ingredients.
2
Heat 2 tablespoons of oil or butter in a griddle or sauté pan over medium heat. Add the onions and cook until softened.
3
Add the mushrooms and another 2 tablespoons of oil. Sauté with the onions for 2 or 3 minutes.
4
Add the sliced steak. Use a spatula to break apart the meat as it cooks, mixing with the mushrooms and onions.
5
When all the steak has browned, lower the heat and lay the slices of provolone down evenly over the steak, mushrooms and onions.
6
When the provolone is half melted, turn off the heat. The residual heat will keep melting the cheese.
7
Pile the steak mixture onto slider buns, top with optional additional cheese sauce, and serve immediately.
