    A Recipe for a....Chicken Sandwich??

    Yes, this is a recipe for a sandwich. But before you walk away, know that this is NOT just any sandwich. It’s a grilled sandwich. It’s a pepper Jack cheesy, herb mayo-slathered, toasty-hot, grilled chicken sandwich and it’s positively otherworldly. And by otherworldly, we mean that you’ll want to escape alone with this peppery, oniony, hearty, melty sandwich to another place—a place where you can be together, where you can enjoy each and every bite of the perfection that is this warm, toasted sandwich in peace and bliss. Lots of homemade chili-herb mayo oozing between crisp, warm bread and pepper Jack cheese melting its way into slices of juicy chicken breast—this warm grilled chicken sandwich is so good that the word “sandwich” can’t even contain it.

    Ingredients

    Chilli Herb Mayo

    • 2 tablespoons minced fresh basil
    • 2 tablespoons minced fresh cilantro
    • 1 tablespoon minced fresh chives
    • 1 cup mayonnaise
    • 1 teaspoon chili powder
    • sea salt
    • freshly cracked black pepper

    Sandwich

    • 1 large red, yellow, or orange bell pepper, cut into 1-inch-thick strips
    • 1 pound boneless, skinless chicken breast
    • ¼ cup extra-virgin olive oil, plus more for brushing
    • 1¼ teaspoons sea salt
    • ½ teaspoon freshly cracked black pepper
    • 1 small yellow onion, thinly sliced
    • 8 slices sourdough bread
    • 1 avocado, sliced
    • 1 large red, yellow, or orange bell pepper, cut into 1-inch-thick strips

    Method

    1. In a small bowl, combine the basil, cilantro, chives, mayonnaise, and chili powder. Season to taste with salt and pepper (see Note).

    2. Preheat the grill to medium-high. Brush the bell peppers and chicken with the olive oil and season with the salt and pepper. Transfer the chicken and peppers to the preheated grill and cook until peppers begin to soften and char and chicken is cooked through, about 4 to 6 minutes per side. Transfer to a cutting board. Allow the chicken to rest for 5 minutes before thinly slicing.

    3. Meanwhile, heat the remaining ¼ cup olive oil in a small skillet over medium-low heat. Once the oil is glistening, add the onions and cook, stirring often, until onions begin to brown and are soft, about 10 minutes.

    4. Making one sandwich at a time, spread the herb mayo on the inside of each slice of bread. On four of the slices, layer the onions, bell peppers, avocado, grilled chicken, and pepper Jack cheese, dividing evenly. Top with the remaining slices of bread, mayo-side down. Brush the tops and bottoms of the sandwiches with olive oil.

    5. Heat a large cast-iron skillet or griddle over medium-low heat. Working in batches, if needed, add the sandwiches and cook, until golden brown and the cheese is melted, about 3-4 minutes per side. Slice each sandwich in half and serve warm.


    Note: Store any unused herb mayo in an airtight container in the refrigerator for up to 1 week.

      What do I do if I don’t have access to a grill?

      You can just cook the chicken in a skillet on the stovetop or broil it in the oven! Hope you enjoy Chloe.
