Mix hoisin, soy, sriracha, honey, garlic, ginger and salt in a medium bowl; stir to fully combine ingredients. Add chicken to marinade and turn to fully cover; let chicken marinate for 15 minutes.

Heat oil on MEDIUM heat in a large skillet. Once oil is very hot, remove chicken from marinade (**MAKE SURE TO SAVE THE MARINADE), and add to hot skillet with the skin side facing down. Cook chicken on both sides; make sure the skin side gets browned very well.

Once both sides of the chicken have been browned, turn the heat down to LOW. Pour the reserved marinade into skillet. Spoon sauce over chicken thighs, and continue to cook. As chicken cooks, the sauce will slightly reduce in volume and thicken up a bit. Cook until chicken is fully cooked through, or reaches an internal temperature of 165° F. If using bone-in thighs, cooking time will be approximately 25 minutes total... slightly less if no bone. Occasionally spoon a bit of sauce over each piece of chicken during the cooking process.

Once chicken is done, remove pan from heat, and transfer chicken to individual serving plates. Garnish chicken with white sesame seeds, if desired. Serve, and enjoy!
