In a small bowl, whisk together soy sauce, honey, minced garlic, grated ginger, sesame oil, salt, and pepper to create the marinade.
In a large bowl, place the chicken thighs and pour half of the marinade over them. Allow the chicken to marinate for at least 15 minutes for maximum flavor.
While the chicken is marinating, spread the sliced bell peppers, red onion, and pineapple chunks on a large sheet pan. Drizzle with the remaining marinade and toss to coat the vegetables and pineapple evenly.
Remove the chicken from the marinade and nestle the thighs among the vegetables on the sheet pan.
Place the sheet pan in the preheated oven and roast for 25-30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C). The vegetables should be tender and slightly caramelized.
Once done, remove the sheet pan from the oven and let it rest for a couple of minutes.
Serve the chicken and vegetables over cooked jasmine rice, garnishing with chopped green onions and sesame seeds for an extra touch.
Notes
Allow chicken to marinate for at least 15 minutes for best flavor.
