These Ginger Chicken Thigh Sandwiches features chicken thighs marinated with a whole whack of ginger snuggled into a potato bun slathered with ponzu mayo and topped with gochugaru spiked pickled onions and cucumbers.
Place the soy sauce, mirin, honey, garlic, and ginger in a bowl and whisk to combine. Pour the mixture over the chicken thighs and toss to coat. Cover and transfer to the fridge. Let marinate for 3 hours or overnight.
Once the chicken is ready, take it out of the marinade. Pour the marinade into a small skillet and bring to a boil and reduce to a simmer. Simmer until the marinade is reduced by half.
While the marinade is simmer, heat your cast-iron griddle or charcoal grill until smoking. Sear the chicken thighs on both sides until grill marks appear. Either reduce the heat or move your chicken to indirect heat and cook until the it registers an internal temperature of 165°F. Brush the chicken all over with the reduced marinade and transfer to a plate and keep warm until ready to serve.
