To make Chili Lime Chicken Tacos, start by adding soy sauce, olive oil, lime juice and lime zest, crushed fresh garlic, spices and sriracha to a large ziptop bag.
Wash, dry and if needed, slice chicken lengthwise and then add to the ziptop bag with your chili lime marinade. Push out the extra air and seal tightly. Move your chicken around to make sure everything is covered in marinade, add your bag to a bowl or pan large enough to hold your chicken and move to the refrigeratore for 1-2 hours.
Once marinated, prepare your grilling method. To make using a grill pan , spray the grill pan with non-stick spray and heat over high heat. Remove your chicken from the marinade (do not discard the marinade!) and add your chicken breasts to the pan and sear for 3-4 minutes each side and then finish them off in a 350 degree oven for 20-25 minutes.
While your chicken is cooking, pour the saved chili lime marinade into a small sauce pan and bring to a boil. Boil for 1-2 minutes and then lower the heat to medium low to simmer while your chicken cooks. Your marinade will start to reduce and thicken slightly. It is imperative you bring the marinade to a full rolling boil to kill any foodborne bacteria.
Once your chicken is cooked, remove from the oven and let sit 5 minutes. Using two forks, shred your chicken breasts and top with the marinade sauce and mix together. Lay out the romaine lettuce leaves and add your chili lime chicken and any toppings your like. Serve immediately.
