• Serves: 2

Ingredients

• 4  portabella mushroom caps, stems removed (8oz total)
• 4  teaspoons  balsamic vinegar

• 2  whole grain buns
• 2  tablespoons pesto sauce
• 4  pieces lettuce greens (optional)

2. Grill mushrooms 8 minutes, turning halfway through and brushing with vinegar.

4. Spread each bun with half of the pesto.
5. Place peppers, mushrooms, and greens (if using) on buns.
6. If desired, drizzle with additional vinegar.
