In a large skillet or wok, heat the sesame oil over medium-high heat. Add the minced garlic and grated ginger, sautéing for about 30 seconds until fragrant.
Add the ground chicken to the skillet, breaking it apart with a spatula, and cook until browned and cooked through, about 5-7 minutes.
Stir in the coleslaw mix and snap peas, cooking for an additional 3-4 minutes until the vegetables are tender but still vibrant.
Pour in the soy sauce and optional sriracha, mixing well to combine all the flavors. Cook for another 2 minutes to allow the sauce to absorb.
Remove from heat and fold in the chopped green onions, reserving some for garnish.
Serve hot, garnished with sesame seeds and fresh cilantro if desired.
