Begin by setting your oven to 400°F. Lightly coat a baking sheet with cooking spray.
Carefully detach the stems from the portobello mushrooms, remove the gills using a spoon, and lightly spray the caps with oil. Season the tops with 1/8 teaspoon of salt and a sprinkle of freshly ground pepper.
Sprinkle salt and pepper evenly over both sides of the steak.
In a large skillet, apply cooking spray and heat it on high. Allow the pan to become very hot before adding the steak. Cook for approximately 1 to 1 ½ minutes on each side, or until the meat is fully cooked.
Once cooked, place the steak on a cutting board and slice it thinly. Set aside for later.
Lower the heat to medium-low, add a bit more oil to the skillet, and sauté the onions and peppers for 5 to 6 minutes, or until they become tender.
In a medium mixing bowl, combine all the ingredients. Spoon the mixture into the mushroom caps, filling each with about ½ cup.
Place the stuffed mushrooms in the oven and bake until the cheese is gooey and the mushrooms are soft, which should take around 20 minutes.
