Mix ground pork, soy sauce, sugar, green onion, garlic, ginger paste, white pepper, and salt in a bowl. Portion into meatballs and chill on a tray for 1 hour or overnight.
Whisk lime juice, olive oil, white vinegar, chili sauce, and soy sauce to make the vinaigrette. Season with salt and pepper. Set aside.
Preheat oven to 350°F. Sear meatballs in a hot skillet on 3 sides for 1 minute each, then transfer to a baking sheet and bake for 5–8 minutes until fully cooked.
Toss cabbage, cucumber, red and green onion, and cilantro with the vinaigrette in a large bowl.
Arrange salad on a platter, add meatballs, garnish with cilantro and lime wedges. Serve immediately.
Notes
You can prep the meatballs the day before and refrigerate overnight for better flavor and easier day-of cooking.
