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.
