Mix the honey, coconut aminos, ginger, garlic, and onion powder in a bowl. Alternating between chicken and pineapple, place all the pieces on the skewers.
Using a pastry brush or spoon, brush the sauce onto the chicken. Place on a medium-heat grill and cook for 8-10 minutes, turning every minute or so to brush on more sauce. Garnish skewers with green onion and serve as-is or with cauliflower rice, if desired.
If using wooden skewers, soak them in water for 30 minutes prior to use, to prevent them from burning.
