01 - Heat a large skillet or wok over medium-high heat. Add the ground pork and cook, breaking it up with a spatula, until browned and cooked through, about 5 to 6 minutes.
02 - Add the chopped onion, garlic, and ginger to the skillet. Sauté for 2 to 3 minutes until fragrant and the onion begins to soften.
03 - Stir in the coleslaw mix. Cook, stirring frequently, until the vegetables are just tender but still retain some crispness, about 4 to 5 minutes.
04 - In a small bowl, whisk together the soy sauce, sesame oil, rice vinegar, sriracha if using, and black pepper until well combined.
05 - Pour the sauce into the skillet, tossing to coat all ingredients evenly. Cook for another 1 to 2 minutes until heated through. Remove from heat and stir in the sliced green onions.
06 - Transfer to serving plates and garnish with toasted sesame seeds and additional green onions if desired. Serve hot.
