Servings : 4
Prep Time 10 mins
Cook Time 20 mins


  • 1.5 pounds skirt or flank steak, cut against the grain into thin slices
  • 2 teaspoons salt
  • 1 teaspoon fresh ground black pepper
  • 3 tablespoons olive oil, divided
  • 1 small yellow onion, thinly sliced
  • 4 cloves garlic, minced or pressed
  • 1 green bell pepper, thinly sliced
  • 1 orange bell pepper, thinly sliced
  • 8 ounces sliced baby portobello mushrooms
  • 1 teaspoon Italian Seasoning
  • 4 slices provolone cheese
  • Sliced green onions, for garnish
  • Chopped fresh parsley, for garnish


  • Season steak with salt and pepper.
  • Heat 1.5 tablespoons olive oil in a large (12 to 14 inch) skillet set over medium-high heat.
    Cast iron skillet works great with this recipe.
  • Add sliced steak to the hot oil and cook for 1 to 2 minutes per side. You may want to do this in batches so that the steak browns and crisps up nicely. If the pan is overcrowded, it will steam the steak.
  • Remove cooked steak from pan and set aside; keep covered.
  • Drain any liquid from the pan and wipe it down.
  • Add remaining olive oil and heat it up over medium-high heat.
  • To the hot oil, add onions, garlic, bell peppers, mushrooms, and Italian Seasoning. Cook for 4 minutes, or until vegetables are soft. Stirring occasionally.
  • Stir steak back into the skillet and give it a minute to heat through.
  • Top mixture with cheese slices; lower heat to medium low, and continue to cook until cheese is melted. You can also pop it under the broiler to get a bit of browning on the cheese.
  • Remove from heat.
  • Garnish with green onions and parsley.
  • Serve.
