Gourmet Portobello Mushroom Burger

Ingredients

Portobello mushrooms

4 large caps

Balsamic vinegar

1/4 cup

Olive oil

2 tablespoons

Garlic

2 cloves, minced

Salt

1/2 teaspoon

Black pepper

1/4 teaspoon

Burger buns

4, whole grain preferred

Mayonnaise

4 tablespoons

Dijon mustard

2 tablespoons

Avocado

1, sliced

Tomato

1, sliced

Red onion

1/2, thinly sliced

Lettuce

4 leaves, romaine or butter lettuce

Instructions

1. In a small bowl, whisk together the balsamic vinegar, olive oil, minced garlic, salt, and pepper to create a flavorful marinade.
2. Remove the stems from the portobello mushrooms and thoroughly brush both sides with the marinade. Allow the mushrooms to marinate for at least 10 minutes to absorb the flavors.
3. Preheat the grill or grill pan over medium heat. Ensure it's well-oiled to prevent sticking.
4. Grill the marinated mushrooms for about 5 minutes per side, or until they are tender and juicy, creating beautiful grill marks.
5. While the mushrooms are grilling, toast the burger buns on the grill for 1-2 minutes until they are golden and crisp.
6. Spread 1 tablespoon of mayonnaise and 1/2 tablespoon of Dijon mustard on the bottom half of each bun.
7. Place a grilled portobello mushroom on each bun, then layer with lettuce, tomato, red onion, and avocado slices for a fresh crunch.
8. Top with the other half of the bun, press gently, and serve immediately while warm.
