8ouncesPortobello mushroom capsabout 4 depending on size
8mini sweet bell peppers
4Cheese slicesif desired
4Hamburger bunstoasted
Additional toppings such as lettuce, tomato, onion, avocado
Instructions
In a large container (or Ziploc bag), mix together mustard, vinegar, oil, salt, pepper and hot sauce. Add the portobellos and peppers, turning gently to coat.
Cover and let sit for 15 minutes to 2 hours (I’ve even done up to 4 in the refrigerator).
Cook mushrooms and peppers, about 5 minutes per side, or until the mushrooms are tender and the peppers are soft and charred. Top mushrooms with cheese last 2 minutes of cooking.
Serve on buns with 2 peppers per burger and any other desired toppings.
