In a small bowl, whisk together the coconut aminos, olive oil, garlic powder, ground ginger, sea salt, and black pepper to create the marinade.
Cut the chicken breast, red bell pepper, and red onion into uniform 1-inch pieces to ensure even cooking on the grill.
Place the chicken pieces in a bowl and toss with half of the prepared marinade, letting it sit for 15 minutes to absorb the flavors.
Thread the chicken, pineapple, pepper, and onion onto skewers, alternating the ingredients for a colorful and balanced presentation.
Grill the skewers over medium-high heat for 10-12 minutes, turning occasionally and brushing with the remaining marinade until the chicken is charred and cooked through.
