Chicken Marinade

Toppings and Sautéed Vegetables

Sandwich Assembly

Method

Marinating Chicken

  1. 1

    Prepare the Marinade

    In a small bowl, mix together olive oil, garlic powder, paprika, salt, and black pepper.

  2. 2

    Marinate the Chicken

    Place the chicken breasts in a zip-lock bag or shallow dish. Pour the marinade over the chicken, ensuring it is well coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes, or up to 2 hours for more flavor.

Grilling Chicken

  1. 3

    Preheat the Grill

    Preheat your grill to medium-high heat.

  2. 4

    Grill the Chicken

    Remove the chicken from the marinade and place it on the grill. Cook for about 6-7 minutes per side, or until the internal temperature reaches 165°F (75°C).

Sautéing Vegetables

  1. 5

    Sauté Onions and Mushrooms

    While the chicken is grilling, heat a skillet over medium heat. Add a splash of olive oil, then add the sliced onions. Sauté for about 2-3 minutes until they start to soften. Add the sliced mushrooms and continue to cook for another 3-4 minutes until both the onions and mushrooms are tender and caramelized.

Assembling the Sandwich

  1. 6

    Combine Ingredients

    Once the chicken is cooked, place it on the bottom half of the burger bun. Top with sautéed onions and mushrooms, followed by two slices of pepper jack cheese. Cover with the top half of the bun.

  2. 7

    Add Fresh Toppings

    Serve the sandwich with lettuce leaves, tomato slices, red onion slices, and pickles on the side.
