Ingredients

Chicken and Seasonings

  • 4 boneless, skinless chicken breast halves
  • 1 tablespoon olive oil
  • 2 teaspoons chili powder
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt

Toppings

  • 1 large avocado, peeled, seeded, and mashed
  • 4 slices provolone cheese (or your favorite kind)
  • 1/2 of a red onion, thinly sliced (or use pickled red onion)
  • 4 leaves leafy green lettuce, washed and patted dry
  • 4 hamburger buns
  • 1 tablespoon lemon juice (to spritz mashed avocado)

Instructions

  1. Chicken seasoning: In a small bowl, mix together the chili powder, garlic powder, onion powder, ground cumin, dried oregano, black pepper, and salt. Lightly coat each chicken breast half with olive oil, then sprinkle the seasoning mixture evenly over both sides of the chicken. Set the seasoned chicken aside while you prepare the grill.
  2. Grill chicken: Preheat a clean grill to medium-high heat and lightly grease the grates to prevent sticking. Place the seasoned chicken breasts on the grill and cook for about 3 to 5 minutes on each side, or until the internal temperature reaches 160°F (71°C) and the chicken is cooked through. Remove the chicken from the grill and place on a plate. Cover with foil to keep warm and allow residual heat to finish cooking the chicken.
  3. Prepare burger toppings: In a small bowl, mash the peeled and seeded avocado until smooth. Add a spritz of lemon juice to the mashed avocado to prevent browning and stir to combine. Thinly slice the red onion if not already prepared, and ensure the lettuce leaves are clean and dry.
  4. Assemble the sandwich: Place a grilled chicken breast on the bottom half of each hamburger bun. Top each chicken piece with a slice of provolone cheese, a generous layer of mashed avocado, red onion slices, and a leaf of lettuce. Finish by placing the top half of the bun on each sandwich. Serve immediately and enjoy the fresh, delicious flavors.

Notes

  • To enhance flavor, let the chicken marinate with the seasoning for 15-20 minutes before grilling if time allows.
  • You can substitute provolone cheese with mozzarella, cheddar, or your preferred cheese.
  • Pickled red onions add a nice tangy contrast if you prefer over raw red onions.
  • For a lighter version, use whole wheat buns or lettuce wraps instead of traditional hamburger buns.
  • Ensure the grill is properly heated and greased to prevent chicken from sticking and to get beautiful grill marks.
