Total Time: 20 mins Preparation Time: 15 mins Cook Time: 5 mins

Ingredients

• 1 cup balsamic vinegar
• 2 tablespoons olive oil
• 1 teaspoon dried basil
• 1/4 teaspoon kosher salt
• 1/4 teaspoon pepper (i just use freshly ground black pepper)
• 2 garlic cloves, minced
• 6 portabella mushroom caps (about 1 1/2 lbs.)
• cooking spray
• 1 tablespoon olive oil
• 1 1/2 cups sliced onions
• 1/4 cup mayonnaise
• 1 teaspoon bottled minced roasted garlic
• 6 whole wheat kaiser rolls or 6 hamburger buns
• 6 curly lettuce leaves
• 6 slices tomatoes

Recipe

• 1 combine first 6 ingredients in a large zip-top plastic bag. add caps to the marinade. seal and marinate in fridge up to 24 hours.
• 2 prepare grill or broiler.
• 3 remove caps and discard marinade. place caps on grill rack or broiler coated with spray. cook 5 minutes or until tender.
• 4 heat oil over medium-high heat. add onion. cover and cook ten minutes or until golden, stirring frequently. (at this point i assume you mix the onions and garlic into the mayo, but i've never actually used this step).
• 5 assemble grilled portabella sandwiches with one cap per bun, plus any lettuce, mayo, tomato, onion, or other garnish that you like. or slice the portabellas into strips and enjoy as a topping for a mixed green salad with onion, tomato, etc.
