Cut the chicken into 1" cubes or leave them whole. Soak wood skewers in water up to 1 day before using them to prevent burning.
In a glass container, mix the garlic, ginger, turmeric, and coconut aminos together until smooth. Add the chicken and turn to thoroughly coat. Marinate up to 1 day.
Preheat the grill to 425-450ºF. While the grill heats, make the peanut sauce by adding all the ingredients listed except the lime juice. Bring to a boil, then lower to a simmer, stirring occasionally until it's thickened, 10-15 minutes.
If you're making skewers, remove them from the soaking water and drain. Thread the chicken cubes on piece by piece leaving a small amount of space between.
Place the chicken on the heated and oiled grill. For whole chicken thighs, grill about 6-8 minutes per side, and around 6 minutes per side for skewers, or until the chicken reaches 165ºF on an instant-read thermometer.
Whisk the lime juice into the finished peanut sauce and serve it with the finished chicken, Instant Pot White Rice, and Asian Cucumber Salad.

Notes
Peanut butter and cashew butter are my favorites for this sauce, but almond butter, pecan butter, or seed butter are all good too.
