Method

Marinating the Mushrooms

  1. 1

    Prepare the Marinade

    In a small bowl, combine balsamic vinegar, olive oil, minced garlic, salt, and black pepper.

  2. 2

    Marinate the Mushrooms

    Place the portobello mushrooms in a shallow dish and pour the marinade over them. Ensure they are well coated. Let them marinate for at least 30 minutes.

Cooking the Spinach

  1. 3

    Sauté Garlic

    In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.

  2. 4

    Cook the Spinach

    Add the fresh spinach to the skillet and season with salt and black pepper. Cook for about 3-5 minutes, stirring often, until the spinach is wilted. Remove from heat and set aside.

Cooking the Mushrooms

  1. 5

    Sauté the Mushrooms

    In the same skillet, add the marinated portobello mushrooms, cooking them for about 5-7 minutes on each side until they are tender and cooked through.

Assembling the Sandwich

  1. 6

    Prepare the Kaiser Rolls

    Slice the kaiser rolls in half and lightly toast them if desired.

  2. 7

    Layer the Ingredients

    On the bottom half of each roll, place a sautéed portobello mushroom cap, a generous portion of sautéed spinach, a few strips of roasted red peppers, and top with provolone cheese.

  3. 8

    Melt the Cheese

    Place the sandwiches under a broiler for 1-2 minutes until the provolone cheese is melted and bubbly.

  4. 9

    Add Pecorino Romano

    Remove from the broiler and sprinkle with pecorino romano cheese before placing the top half of the rolls on.
