Cut the chicken breast into 1-inch cubes and season with sea salt, black pepper, and garlic powder.
Chop the red bell pepper, red onion, and pineapple into uniform chunks suitable for skewering.
In a small bowl, whisk together the coconut aminos, honey, sesame oil, and ginger powder to create the glaze.
Thread the chicken, pineapple, peppers, and onions onto skewers, alternating items for even cooking.
Heat a grill pan or outdoor grill over medium-high heat and lightly coat with avocado oil.
Grill the skewers for 10-12 minutes, turning occasionally and brushing with the glaze during the last 3 minutes until the chicken is cooked through and the pineapple is caramelized.
Serve the skewers over a bed of cooked jasmine rice.
