Whisk sweet chili sauce, soy, 1½ tbsp lime juice, rice vinegar, honey, garlic, ginger, red pepper, and 1 tbsp oil. Reserve 1/4 cup for glazing.
Pat chicken dry, season with salt and pepper, then coat with the remaining marinade. Chill 20–30 minutes.
Preheat grill to medium-high. Clean and oil grates with the vegetable oil.
Grill chicken 5–6 minutes per side until charred in spots and 165°F inside. Brush with reserved glaze during the last 2 minutes.
Rest 5 minutes. Sprinkle green onions and sesame, then drizzle the remaining 1 tbsp lime juice. Serve hot.
Notes
Variation: Swap thighs for pounded chicken breasts and grill 4–5 minutes per side. For extra tang, add 1 tbsp pineapple juice to the marinade. To bake, roast at 425°F for 18–20 minutes, broiling briefly to caramelize. Leftovers keep 3–4 days chilled; rewarm gently to avoid drying.This recipe is an original creation inspired by classic Sweet Chili Grilled Chicken Recipe flavors.
