Combine ground beef or chicken, breadcrumbs, minced garlic, grated ginger, salt, pepper, and a beaten egg in a bowl.
Shape the mixture into evenly sized meatballs.
Heat oil in a skillet and cook the meatballs until browned and fully cooked.
In a small bowl, mix soy sauce, chili sauce, honey, rice vinegar, and a little sesame oil.
Pour the sauce into the skillet and simmer for 3–5 minutes until slightly thickened.
Add the meatballs and toss gently until they are evenly coated with the spicy sauce.
Garnish with sesame seeds and chopped green onions. Serve hot with rice, noodles, or vegetables.
