Heat oil in large skillet over medium-high heat. Add ground meat and cook until no longer pink, breaking it up as it cooks.
Stir in onion, garlic, and ginger. Cook 2 to 3 minutes until fragrant.
Add red pepper, cabbage, and carrots. Continue cooking 5 to 7 minutes, stirring often, until cabbage softens but still has a little bite.
Add soy sauce, rice vinegar, sweet chili sauce, and chili flakes. Taste and adjust to your liking.
Remove from heat. Drizzle with toasted sesame oil. Top with green onions and sesame seeds or chopped cashews.
