Increase the heat to medium-high and add the ground chicken to the skillet. Cook until it’s no longer pink, breaking it apart with a spatula, about 5-7 minutes.
Stir in the chopped red bell pepper, green onions (saving some for garnish), chili garlic sauce, soy sauce, honey, salt, pepper, and rice vinegar. Mix well and let it cook for another 3-4 minutes.
If you prefer a thicker sauce, mix the cornstarch with water in a small bowl until smooth, then add it to the skillet. Cook for an additional 2 minutes, stirring constantly, until the sauce thickens.
Remove from heat and transfer to a serving platter. Garnish with sesame seeds and the reserved green onions.
Notes
Adjust the chili garlic sauce to your preferred spice level.
