Sandwich Ingredients

Method

Preparation Steps

  1. 1

    Marinate the Mushrooms

    In a bowl, whisk together olive oil, balsamic vinegar, minced garlic, salt, and black pepper. Add the portabella mushrooms, ensuring they are well coated. Cover and let marinate for at least 30 minutes.

  2. 2

    Grill the Mushrooms

    Preheat a grill or grill pan over medium-high heat. Remove the mushrooms from the marinade and grill them for about 5-7 minutes on each side, or until tender and nicely charred.

  3. 3

    Melt the Cheese

    During the last minute of grilling, place a slice of Swiss American cheese on each mushroom and close the grill lid to allow the cheese to melt.

  4. 4

    Assemble the Sandwich

    Toast the hamburger buns lightly on the grill. Place the grilled mushrooms with melted cheese on the bottom half of each bun. Top with the other half of the bun.

  5. 5

    Serve

    Serve the sandwiches warm with spicy herb-lemon aioli on the side or spread on top, if desired.
