Heat the sesame oil in a large cast iron pan or skillet over medium-high heat.
Add the ground chicken and cook 4–5 minutes, breaking it up with a spoon, until no longer pink and cooked through.
Add the sliced or minced green onion and the minced garlic; sauté 1–2 minutes until fragrant.
Stir in the ground ginger until evenly distributed.
Add the coleslaw mix, gluten-free soy sauce (or alternative), and rriracha; toss to combine.
Cook, stirring occasionally, until the coleslaw softens to your desired tenderness, about 3–5 minutes.
Taste and adjust with more soy sauce or rriracha if desired, then serve.
