Mix the marinade ingredients together and pour in a large ziplock bag over the chicken thighs.
Let it marinade for 2 hours in the fridge.
Heat a grill or a cast iron skillet over medium-high heat. Cook the chicken thighs for about 3 minutes per side, or until the internal temperature reached 160°F.
Remove from heat and let them rest for 5 minutes.
Slice the thighs into strips and serve on warmed tortillas with the toppings of your choice.
Notes
Do not marinade the chicken for more than 3 hours as the citrus will start to change the texture of the chicken.
You can use a broiler to cook the thighs as well. Just broil them until the internal temperature reaches 160°F, making sure they don't burn on the outside.
You can use corn or flour tortillas for these tacos.
Heat up your tortillas on the cast iron skillet for the best results - warm them until light golden brown on the outside. If using corn, you may need to add some oil to the pan to heat them properly.
Marinade the chicken anywhere from 30 minutes to 3 hours for the best results.
Make these crispy chicken tacos by filling the tortillas with the chicken, then frying them in oil until golden brown on the outside - flip and brown on second side as well.
