- 0.5 cup Mayonnaise
- 10 pieces Fresh basil leaves
- 1 teaspoon Lemon juice
- 4 pieces Burger buns
- 4 pieces Lettuce leaves
- 8 pieces Tomato slices

Directions
Step 1
Clean the portabella mushroom caps by gently wiping them with a damp paper towel. Remove the stems if still attached.
Step 2
In a small bowl, whisk together the olive oil, balsamic vinegar, garlic powder, salt, and black pepper.
Step 3
Brush the marinade mixture generously onto both sides of each mushroom cap. Set aside to marinate for 10 minutes.
Step 4
Meanwhile, prepare the basil mayonnaise by combining mayonnaise, chopped fresh basil leaves, and lemon juice in a food processor. Blend until smooth. Set aside.
Step 5
Preheat your grill or grill pan to medium-high heat.
Step 6
Place the marinated mushroom caps on the grill, gill side down. Cook for about 4-5 minutes per side, or until tender and slightly charred. Remove from the grill and set aside.
Step 7
Lightly toast the burger buns on the grill, cut side down, for about 1 minute, until golden brown.
Step 8
To assemble the burgers, spread a generous layer of basil mayonnaise on the bottom half of each bun.
Step 9
Place a grilled portabella mushroom cap on top of the basil mayonnaise.
Step 10
Layer with a lettuce leaf, 2 tomato slices, and a slice of red onion.
Step 11
Top with the other half of the bun and serve immediately.
