Preheat oven to 400 degrees F
To make the sauce: In a small saucepan, heat soy sauce, sweet chili sauce, honey, garlic and ginger on medium heat and bring to a boil. Turn down heat and allow sauce to simmer, whisking occasionally until sauce is thickened. Remove from heat.
Spread chicken and chopped veggies on a baking sheet sprayed with cooking spray and season with salt and pepper. Drizzle half of the sauce over the chicken and veggies and toss to combine.
Bake in oven for 20 minutes, tossing halfway through, and continue cooking until veggies are tender and chicken is cooked through.
Drizzle remaining sauce over top and sprinkle with sesame seeds and green onions.
