  • 4 large portobello mushroom caps, 5 inches in diameter

  • 1/3 cup balsamic vinegar 

  • 1/2 cup water 

  • 1 tablespoon sugar 

  • 1 clove garlic, minced

  • 1/4 teaspoon cayenne pepper (optional)

  • 2 tablespoons olive oil 

  • 4 whole-wheat buns, toasted

  • 4 slices tomato 

  • 4 slices red onion 

  • 2 Bibb lettuce leaves, halved



  • Clean the mushrooms with a damp cloth and remove the stems. Place on a dish, stemless side up.

  • To make the marinade, whisk the vinegar, water, sugar, garlic, cayenne pepper, and olive oil in a small bowl. Drizzle over the mushrooms, cover, and marinate 1 hour in the refrigerator, turning the mushrooms once.

  • Heat the gas grill or broiler. Lightly coat the grill rack or broiler pan with cooking spray and position it 4-6 inches from heat source.

  • Grill or broil the mushrooms on medium heat, 5 minutes on each side until tender. Baste with the marinade to keep moist. Transfer the mushrooms with tongs to a plate.

  • Place each mushroom on a bun, topping with the tomato, red onion, and lettuce. Serve immediately.
