Ingredients
  

  • 3 tbsp olive oil
  • 4 portobello mushroom caps
  • 1 yellow onion sliced
  • 1 red onion sliced
  • 2 tbsp soy sauce
  • salt and pepper to taste
  • 1 lb sirloin steak sliced
  • 4 oz provalone
  • parsley fresh, chopped

Instructions
 

  • Preheat your oven to 375F and line a baking sheet with parchment paper.
  • Scrape out the stem and gills of the mushrooms. Brush the mushroom caps with olive oil and season with salt and pepper.
  • Season the steak with salt and pepper to taste.
  • Set a large skillet over medium-high heat and add olive oil. When the oil is hot enough to shimmer, add the steak and sear each side until browned, about 5 minutes each.
  • When the steak is cooked, remove from the pan and let rest.
  • Add 1 tbsp oil to the pan and add onions and peppers. Cook for about 5 minutes until the onions are translucent and the veggies are tender. Set aside.
  • Thinly slice the steaks. Add to a bowl with the veggies and the soy sauce and toss to combine.
  • Place the mushroom caps on the baking sheet, hollow side up. Spoon the steak and veggie mixture into the caps, and then sprinkle generously with cheese.
  • Bake 12-15 minutes, or until the cheese is melted and the mushrooms are tender.
  • Sprinkle with fresh parsley and serve hot.
