In a large skillet or wok, heat the sesame oil over medium-high heat.
Add the ground chicken and diced onion. Cook, breaking up the meat with a spatula, until the chicken is browned and the onion is translucent.
Add the minced garlic and grated ginger. Sauté for 1 minute until fragrant.
Stir in the coleslaw mix, soy sauce, rice vinegar, and sriracha.
Cook for 5-7 minutes, stirring frequently, until the cabbage is wilted to your desired tenderness.
Remove from heat and garnish with sliced green onions and toasted sesame seeds. Serve immediately.
