This grilled portobello sandwich is perfect for summer. You can use just about any type of bread but kaiser rolls or burger buns are the best. I like to serve this with grilled squash and a glass of white wine.

Original recipe (1X) yields 6 servings

⅓ cup balsamic vinegar
¼ cup olive oil
1 tablespoon minced garlic
6 portobello mushroom caps
½ cup mayonnaise
2 tablespoons chopped fresh basil
1 tablespoon Dijon mustard
1 teaspoon lemon juice
6 kaiser rolls, split, toasted
1 tablespoon butter, softened, or as needed
6 leaves lettuce
6 tomato slices

Directions

Preheat an outdoor grill for medium heat and lightly oil the grate.
Whisk vinegar, oil, and garlic together in a small bowl.
Arrange mushrooms on a baking sheet with the gills facing up; brush with about 2/3 of the marinade and let sit for 3 to 5 minutes.
Transfer mushrooms to the preheated grill with the gills facing down; grill, basting occasionally with remaining marinade, until tender, about 4 minutes per side.
While the mushrooms are cooking, mix mayonnaise, basil, Dijon, and lemon juice together in a small bowl. Butter toasted rolls, then spread with mayonnaise mixture.
Remove mushrooms from the grill and place on bottom buns. Top with lettuce, tomatoes, and top buns.
