Ingredients
- 2 teaspoons Olive Oil Divided
- 16 ounces Portobello Mushroom Sliced
- 1 1/2 teaspoons Dried Rosemary
- 2 tablespoons Balsamic Vinegar
- 1 large Onion Thinly sliced
- 1/2 cup Chopped Roasted Red Peppers
- 4 ounces White Cheddar Cheese
- 1/3 cup Mayonnaise
- 2 cloves Garlic Minced
- 1/4 teaspoon Salt
- 1/2 teaspoon Black Pepper
- 4 Soft Bakery-Style Hamburger Bun
Instructions
- Heat olive oil in a large skillet over medium heat.
- Add mushrooms, rosemary and vinegar. Cook until mushrooms have softened, about 8-10 minutes. Remove mushrooms and set aside.
- Add another teaspoon of olive oil to the same skillet. Add onion to the pan. Heat onions until soft and caramel in color. This should take about 10-15 minutes.
- At the 10 minute mark, add your red peppers and continue to cook just until the mixture is heated through.
- Spray a grill pan with non-stick spray and heat on medium low. Add mushrooms, arranging them into two “piles”. (Reserve remaining mushrooms)
- Top each pile with onion mixture and 2 oz of cheese. Place a deep skillet cover over the piles and allow cheese to melt.
- Meanwhile toast your hamburger buns.
- In a small bowl, combine mayo, garlic and salt. Stir. Place about a 1/2 tablespoon of mayo mixture on each half of your bun.
