Cooking Instructions

  1. 1

    Prepare the Vegetables

    In a skillet over medium heat, add olive oil. Once hot, add the sliced onions and bell peppers. Sauté until softened, about 5-7 minutes.

  2. 2

    Cook the Mushrooms

    Add the sliced Pebble Creek mushrooms to the skillet with the onions and bell peppers. Season with salt and black pepper. Cook until the mushrooms are browned and tender, about 8-10 minutes.

  3. 3

    Assemble the Sandwich

    Preheat a grill or grill pan. Slice the baguette lengthwise. Spread the steakhouse aioli on the inside of both halves. Layer the mushroom mixture evenly on one half of the baguette.

  4. 4

    Add Cheese and Grill

    Sprinkle the Gouda and white cheddar cheese over the mushroom mixture. Close the sandwich and grill for about 3-4 minutes on each side until the cheese melts and the bread is golden brown.

  5. 5

    Serve

    Remove the sandwich from the grill, drizzle with balsamic glaze, and slice into portions. Serve warm.
