Prep the Roasted Pork Belly
Cut pork belly into bite-sized cubes if it is not yet.
Heat a large skillet or wok over medium-high heat.
Add the pork belly cubes and let them render and get even more crisp in their own fat, turning until golden. Spoon off excess fat if needed.
Make the Sticky Chili Sauce
In a small bowl, whisk together soy sauce, hoisin, oyster sauce, honey, vinegar, sesame oil, garlic, ginger, and chicken stock.
Stir in 2 tablespoons chili crisp (optional: save the last tablespoon for garnish at the end).
Glaze and Caramelize
Pour the sauce over the pork belly in the pan.
Let it bubble and reduce, stirring occasionally, until it clings to the pork (about 5–8 minutes).
Finish & Garnish
Toss in the extra spoonful of chili crisp right before serving for that crunchy, fiery topping.
Sprinkle with sesame seeds and green onions.
