In a medium bowl, whisk together the honey, soy sauce, minced garlic, and minced ginger until well combined.
In a large skillet, heat olive oil over medium heat. Season the chicken thighs with salt and pepper on both sides.
Add the seasoned chicken to the skillet and sear for about 5 minutes on each side, or until golden brown.
Pour the honey garlic sauce over the chicken in the skillet. Bring to a simmer, then reduce the heat to low.
In a small bowl, mix the cornstarch with 2 tablespoons of water to create a slurry. Add this slurry to the skillet and stir well to combine.
Continue to cook for another 5-7 minutes, allowing the sauce to thicken and the chicken to cook through. The internal temperature of the chicken should reach 165°F (75°C).
Once the chicken is cooked and the sauce is thickened, remove from heat and let it rest for a few minutes.
Slice the chicken and drizzle any remaining sauce over the top. Garnish with sliced green onions and sesame seeds.
