01 - Whisk together soy sauce, hoisin sauce, rice vinegar, brown sugar, cornstarch, chicken broth, sriracha, and sesame oil in a bowl until smooth. Set aside until ready to use.
02 - Heat vegetable oil in a large skillet or wok over medium-high heat. Add ground chicken and cook, breaking it up with a spatula, until no longer pink, approximately 5 minutes.
03 - Add minced garlic, grated ginger, and the white parts of the green onions to the skillet. Stir-fry for 1-2 minutes until fragrant.
04 - Pour the prepared sauce into the pan. Stir thoroughly to combine and simmer for 2-3 minutes until sauce thickens and coats the chicken evenly.
05 - Serve hot over steamed rice or cauliflower rice. Garnish with sesame seeds and reserved green onion tops.
