Sandwich Ingredients

Method

Preparation Instructions

  1. 1

    Prepare the Roasted Garlic Mayo

    In a small bowl, mix mayonnaise with minced garlic. Add salt and pepper to taste and set aside.

  2. 2

    Sauté the Onions

    In a skillet over medium heat, add 1 tablespoon of olive oil. Add sliced onions and sauté until caramelized, about 10-15 minutes. Set aside.

  3. 3

    Grill the Portabella Mushrooms

    Brush the portabella mushrooms with remaining olive oil and season with salt and pepper. Grill on medium-high heat for about 5-7 minutes on each side until tender.

  4. 4

    Assemble the Sandwich

    On a slice of bread, spread a generous amount of roasted garlic mayo. Layer with grilled portabella, sautéed onions, and a slice of jack cheese. Top with another slice of bread.

  5. 5

    Grill the Sandwich

    In the same skillet used for the onions, add a little more olive oil and grill the sandwich on medium heat for about 3-4 minutes on each side, or until the bread is golden brown and the cheese has melted.

  6. 6

    Serve

    Remove the sandwich from the skillet, slice in half, and serve hot with additional roasted garlic mayo on the side if desired.
