If using chicken breasts, we sliced them horizontally to make them thinner for quicker grilling and also to avoid drying out the chicken breasts while cooking. Chicken thighs are juicy already and we don’t usually thin out the chicken thighs.
Stir together all marinade ingredients (oil, fish sauce or soy sauce, oyster sauce or hoisin, brown sugar, garlic, onion powder, curry powder, salt, and pepper), in a bowl or large ziplock bag.Add chicken and to the marinade and chill for at least 30 minutes or overnight.
Pre-heat grill to medium-high heat. Scrape the grill grates to make sure they are clean.
Remove chicken from plastic bag/bowl and discard excess marinade. Grill the chicken for about 2-4 minutes per side, or until slightly charred and the chicken is cooked through.
Sprinkle chopped cilantro on chicken and serve in a sandwich, or with a side of veggies or rice. Or make it into a taco!
