“A light vegetarian sandwich with great flavor that is perfect for summer. You can use just about any type of bread but Kaiser rolls or burger buns are best. I like to serve this with grilled squash and a glass of white wine!” - by Rotorwife

Original recipe yields 6 sandwiches
Directions
- Preheat an outdoor grill for medium heat, and lightly oil the grate. Whisk together the balsamic vinegar, olive oil, and garlic in a small bowl.
- Arrange the portobello mushrooms gill-side up on a tray or baking sheet. Brush the mushrooms with some of the vinegar mixture, and allow to marinate for 3 to 5 minutes.
- Place the marinated mushrooms on the preheated grill, gill-side down. Grill mushrooms until tender, brushing both sides of the mushrooms with the remaining marinade, about 4 minutes on each side.
- Mix the mayonnaise, dijon mustard, lemon juice, and basil in a small bowl. Butter the toasted kaiser rolls, then spread with the mayonnaise mixture. Divide the mushrooms, lettuce, and tomato slices evenly to make 6 sandwiches.

"DEEEEELICIOUS! The basil mayo makes this sandwich, and just puts it over the top. I used sliced portobello mushrooms because that's all the store had this week. I marinated them in the basalmic mixtur..." See moree for about an hour before cooking and they had a wonderful flavor. I did decrease the olive oil to about 2 tbsps. because I was trying to watch the fat and I used light mayo in the basil mayo with great results. This is a definate keeper! Thanks for sharing. :)"

"Delicious! Very satisfying on a hot summer night. The only changes I made were 1) to marinade the mushrooms in the vinegar/oil/garlic for 2 hours instead of just brushing it on before grilling. The mu..." See moreshrooms were very flavorful that way, and 2) to add a slight amount of cheese (pick your favorite) onto the mushrooms just before taking off the grill. I loved the mayo, and will look for other ways to use it!"
