These burgers are a wonderful alternative to traditional beef burgers. The meaty texture of the portabella mushrooms pairs perfectly with the creamy and spicy red pepper mayonnaise, making each bite a burst of flavor.

Ingredients
- 4 large portabella mushroom caps
- 2 tablespoons olive oil
- Salt and pepper, to taste
- 4 whole wheat buns
- 1 cup fresh spinach or arugula
- 1 medium tomato, sliced
- 1/2 red bell pepper, roasted
- 1/2 cup mayonnaise
- 1 teaspoon garlic powder
- 1 teaspoon lemon juice
Instructions
- Begin by preheating your grill or stovetop grill pan over medium-high heat.
- Clean the portabella mushroom caps by gently brushing off any dirt and removing the stems. Drizzle with olive oil and season with salt and pepper.
- Grill the mushrooms for about 5-7 minutes on each side, or until they’re tender and have nice grill marks. Remove them from the heat and set aside.
- To make the red pepper mayonnaise, simply blend the roasted red bell pepper with the mayonnaise, garlic powder, and lemon juice in a bowl until smooth. Add salt and pepper to taste.
- Now, it’s time to assemble the burgers. Toast the whole wheat buns lightly if desired.
- Spread a generous amount of red pepper mayonnaise on the bottom half of each bun.
- Layer on the grilled portabella mushrooms, followed by fresh spinach (or arugula) and tomato slices.
- Top with the other half of the bun and serve immediately.
