Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a large mixing bowl, combine ground beef with minced garlic, grated ginger, chopped green onions, egg, and breadcrumbs. Add soy sauce, sesame oil, gochujang, brown sugar, rice vinegar, salt, and black pepper. Mix gently but thoroughly.

Scoop portions of the meat mixture and roll into 1-inch meatballs, arranging them on the baking sheet.

Bake the meatballs for 18–20 minutes until golden brown and cooked to an internal temperature of 160°F (70°C).

In a separate bowl, combine mayonnaise, lime juice, and honey. Whisk until smooth and adjust consistency as needed.

Serve the warm meatballs drizzled with the spicy mayo dip or on the side for dipping. Garnish with toasted sesame seeds and chopped scallions.
