Creating Sweet Chili Roasted Chicken and Vegetables is as simple as following these steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Chicken: Pat the chicken thighs dry with paper towels. This helps to achieve a crispy skin. Season both sides with salt and pepper.
3. Prepare Vegetables: Chop the mixed vegetables into bite-sized pieces.
4. Make the Sauce: In a small bowl, whisk together the sweet chili sauce, olive oil, soy sauce, honey (if using), and minced garlic.
5. Combine Ingredients: In a large mixing bowl, toss the vegetables with half of the sauce until evenly coated.
6. Arrange on Baking Sheet: Place the seasoned chicken thighs on a baking sheet. Arrange the coated vegetables around the chicken.
7. Add Remaining Sauce: Drizzle the remaining sauce over the chicken for extra flavor.
8. Bake: Place the baking sheet in the preheated oven and roast for 30-35 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the vegetables are tender.
9. Broil for Crispiness: If desired, switch to broil for an additional 3-5 minutes to crisp the chicken skin and caramelize the vegetables.
10. Rest and Garnish: Remove from the oven and let the chicken rest for a few minutes. Garnish with chopped cilantro or green onions before serving.
