In a large metal bowl, mix together all the marinade ingredients and season with salt and pepper. Taste the marinade before adding the chicken to see if it needs more salt or vinegar. You want to be able to just barely taste both.
Preparing The Burger Toppings & Marinating The Chicken Breasts
Take the raw chicken breasts and slice them in half horizontally.
Place the sliced chicken in the marinade, making sure it is fully submerged. Refrigerate the marinating chicken breasts for 15 minutes.
Prepare your burger toppings by slicing the tomato, washing the lettuce, cutting the cheese, and making sure your burger buns are ready to go.
Pre-heat your BBQ or Cast Iron Grill and make sure it is HOT!
Grilling The Marinated Chicken
Once the chicken breasts have marinated, take them out of the bowl, and place them on a plate to drip off.
Place the chicken breasts on the hot grill and cook on each side for 6 to 8 minutes. The grilled chicken breast should have nice grill marks on it before flipping so make sure to peek under first and letting it cook longer if they are not ready.
Once the chicken has fully cooked, assemble your grilled chicken burgers and serve immediately.
