Make Marinade: Add gochujang, pineapple, sesame oil, honey, soy sauce, fish sauce, garlic, and ginger to a Vitamix or blender. Blend until a thick marinade is created.
Prep Chicken: Cut chicken thighs into 2 inch peices.
Marinate: Add chicken to a large ziplock bag and then pour in the marinade. Mix the bag with your hands and then let it marinate in the fridge for 30-60 minutes, or up to overnight.
Prep Onions: Slice the green onions into 1 1/2 - 2 inch pieces. We prefer to use the white and light green parts of the onion as they hold up the best to grilling.
Skewer: If using bamboo or wooden skewers, let them soak in water for at least 30 minutes before grilling. When ready to grill, add the chicken and all of the marinade to a medium sized bowl. Skewer 1 piece of chicken and 1 piece of green onion, and repeat to fill the skewer. Save the excess marinade.
Grill: Preheat the grill on high to allow the grill grates to completely heat up. Lightly oil the grates. Add the skewers over the direct heat and grill for 6 minutes or until the meat easily separates from the grill. Baste the skewers with the excess marinade and then grill for another 6 minutes on the other side.
Serve and Enjoy!
