4 portobello mushrooms, stems on

2 teaspoons grill seasoning

2 tablespoons canola oil

1 tablespoon chopped garlic

2 teaspoons Worcestershire sauce

2 tablespoons red wine vinegar

1/2 cup grated Cheddar

1/4 cup mayonnaise

4 hamburger buns, toasted

4 leaves romaine lettuce

1 tomato, sliced


  1. Rub the mushroom caps with a damp cloth to clean. Remove stems and reserve for Round 2 recipe "Stuffed Zucchini".
  2. In a small bowl combine the grill seasoning, oil, garlic, Worcestershire sauce and vinegar. Brush over the mushrooms making sure to coat completely. Reserve 2 tablespoons of the marinade for the aioli.
  3. Heat a grill pan or outdoor grill on medium heat. Put the mushrooms, gill side down, onto the grill and grill about 4 to 5 minutes on each side. After you flip the mushrooms top each with 2 tablespoons of Cheddar.
  4. While the mushrooms are grilling, make the aioli sauce by combining the remaining 2 tablespoons of the marinade with the mayonnaise in a small bowl. Spread each hamburger bun with aioli sauce. Remove mushrooms from the grill and serve on the toasted buns with lettuce and tomato slices.
