Ingredients

• 1 tsp vegetable oil
• 1 cup sliced mushrooms
• 1 yellow onion, diced
• 1 green bell pepper, diced
• 2 garlic cloves, minced
• 1 lb extra lean ground beef
• 1/2 cup beef broth
• 1 tbsp cornstarch
• 2 tbsp steak sauce
• 1 tbsp hot sauce (optional)
• 4 hamburger buns
• 4 slicels provalone cheese
• 1/4 red onion, diced

Preparation

In a large skillet, heat the oil over medium-high heat. Add the mushrooms and cook, stirring, until they are golden, about 3 to 4 miniutes. Remove the mushrooms from the skillet and set them aside.
To the same skillet, stir in the onions and green bell pepper. Cook, stirring, until they begin to soften, about 3 minutes. Add the garlic and ground beef to the skillet. Cook the beef, breaking it up with the side of a spoon, until it is no longer pink, about 5 minutes. Return the mushrooms to the skillet and add the beef broth, steak sauce, and hot sauce. Sprinkle in the cornstarch and cook, stirring, until the liquid reduces slightly, about 3 minutes.
Serve immediately on the buns, topped with the provalone cheese and red onions or store in the refrigerator for up to 3 days.
