Heat olive oil in a large skillet or wok over medium-high heat.
Add ground pork and diced onion to the skillet. Cook until pork is browned and onions are translucent, breaking the meat into small crumbles.
Stir in the minced garlic and grated ginger, cooking for 1 minute until fragrant.
Add the shredded coleslaw mix, soy sauce, rice vinegar, and sriracha to the pan.
Sauté for 5-7 minutes, stirring frequently, until the cabbage is wilted but still retains a slight crunch.
Remove from heat and stir in the toasted sesame oil.
Garnish with sliced green onions and serve immediately.
