"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!"

  1. 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.
  2. 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.
  3. 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.
  4. 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.

I've made this recipe several times already this summer, and it is delicious! The only change I made was not buttering the buns, and toasting them on the grill. The mayo combo is so good, I use ...

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 ...

The best portobello sandwich I ever had! I served it on artisan bread, warm from the grill. I made bruschetta with the leftover bread and basil, but used that as the bun for my leftover portobel...

Scrumptious! I enjoyed mine exactly as the recipe was written; my husband and kids wanted to put some cheese on their mushrooms as they were grilling (Swiss). High fives all around ... we will...

WOW - these are fabulous! I love portobello mushrooms, so I had to give this a try. Plus they're so easy to put together. It's great for lunch or a quick weeknight meal. I would recommend marina...

Great recipe! First time we made it we accidentally mixed all ingredients together and cooked the mushrooms in all of it instead of having the mayo mix on its own. They were actually better this...

This was easy, and delicious. I've made it twice, exactly as written - no changes. I toyed with the idea of adding a slice of melty cheese, but haven't yet. I like the idea of a mostly vegan ...

I thought this was a great "burger"! I have always loved portobello sandwiches and this was no different. It was very easy to make, especially the smaller portobellos. I'm not sure how to tel...
