Mushroom Filling

Method

Mushroom Filling

  1. 1

    Prepare the Vegetables

    Thinly slice the Hamakua mushrooms, bell pepper, and onion.

  2. 2

    Sauté the Vegetables

    In a large skillet, heat the olive oil over medium heat. Add the sliced onions and bell peppers, and sauté for about 5 minutes until they start to soften.

  3. 3

    Add Mushrooms

    Add the sliced Hamakua mushrooms to the skillet. Season with salt and black pepper. Continue to sauté for another 5-7 minutes until the mushrooms are tender and cooked through.

Cheese and Aioli

  1. 4

    Prepare the Cashew Aioli

    Soak the cashews in water for at least 2 hours or overnight. Drain and rinse them.

  2. 5

    Make the Aioli

    In a blender, combine the soaked cashews, roasted garlic, lemon juice, water, and salt. Blend until smooth and creamy. Adjust the consistency with more water if necessary.

  3. 6

    Melt the Cheese

    Once the mushroom filling is cooked, lower the heat and add the fresh mozzarella cheese (or vegan cashew mozzarella) on top. Cover the skillet with a lid and let it melt for 2-3 minutes.

Assembly

  1. 7

    Toast the Rolls

    While the cheese is melting, slice the Sun Dog bakery rolls and toast them lightly in the oven or on a grill.

  2. 8

    Assemble the Cheesesteak

    Spoon the mushroom and cheese mixture onto the bottom half of each toasted roll. Drizzle with roasted garlic cashew aioli, then place the top half of the roll on.

  3. 9

    Serve

    Serve the Hamakua Mushroom Cheesesteak with your choice of side, such as fries or a salad.
