Prepare the chicken thighs by trimming any excess fat and patting them dry with paper towels.
In a mixing bowl, whisk together honey, soy sauce, apple cider vinegar, garlic powder, and crushed red pepper flakes.
Season the chicken thighs on both sides with salt and black pepper.
Heat a large skillet over medium-high heat and add a drizzle of oil.
Place the chicken thighs in the skillet and cook for about 5-6 minutes on each side.
Pour the honey-pepper sauce over the chicken in the skillet.
Reduce the heat to low and allow the chicken to simmer for about 5 more minutes, spooning sauce over the chicken occasionally.
Remove the skillet from the heat and let the chicken rest for a few minutes.
Garnish with chopped green onions and serve warm.
