Instructions:
Step 1
First, heat olive oil in a large skillet over high heat, then lower the heat to medium and add the onions, sautéing them for one minute.
Step 2
Then, include the peppers and mushrooms, stir, and continue cooking until the mushrooms become browned and the onions become translucent.
Step 3
After that, continuously stir the mixture, and introduce the steaks and cook for about 3 minutes, or until the meat takes on a light brown color, then, season with salt and pepper to taste.
Step 4
In this step, lay the provolone slices on top of the meat and let them melt (If you’re using cheese that sizzles, melt it in a double boiler before adding it to the dish).
Step 5
Next, slice the bread lengthwise and toast it. Then, distribute the meat mixture evenly between the two pieces of bread.
Step 6
Finally, if you have melted cheese, sprinkle half of it on each piece of bread.
