  • 6 ounces - sirloin steak
  • 1/8 teaspoons - kosher salt
  • 3/4 cups - diced onion
  • 3/4 cups - diced green pepper
  • 1/4 cups - light sour cream
  • 2 tablespoons - light mayonnaise
  • 1/4 cups - light cream cheese, softened
  • 1/3 cups - shredded mild provolone cheese, or your favorite shredded cheese
  • 4 - medium portobello mushrooms, without cracks
  • Directions:

    Preheat oven to 400 degrees F; spray baking sheet with cooking oil.

    Gently remove stems from mushrooms, scooping out the insides. Spray tops of mushrooms with cooking oil, then season with a dash of salt and pepper.

    Season steak with salt and pepper. Spray a large skillet with cooking spray and set on high heat; when pan is very hot, add steak and cook for 1 to 1-1/2 minutes on each side until cooked through. Transfer to cutting board and slice thin; set aside.

    Reduce skillet heat to medium-low, spray with a little more oil and add the onions and peppers, cooking 5 to 6 minutes until soft.

    Combine all ingredients in a medium bowl, mixing together well. Transfer about 1/2 cup of mixture into each of the prepared mushroom caps.

    Bake in preheated oven until cheese melts and mushrooms are tender, about 20 minutes or so.
