Creating Korean BBQ Meatballs with Spicy Mayo Dip is straightforward. Just follow these easy steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Mix Ingredients: In a large mixing bowl, combine ground beef or pork, breadcrumbs, green onions, garlic, ginger, soy sauce, sesame oil, brown sugar, egg, salt, and pepper.
3. Shape the Meatballs: Using your hands, mix thoroughly until well combined. Form the mixture into small balls, about 1 inch in diameter, and place them on the prepared baking sheet.
4. Bake: Bake the meatballs in the preheated oven for 20-25 minutes or until cooked through and golden brown. Use a meat thermometer to ensure they reach an internal temperature of 160°F (70°C).
5. Prepare the Spicy Mayo Dip: While the meatballs are baking, combine mayonnaise, Sriracha, lemon juice, sesame oil, and salt in a small bowl. Mix until smooth and adjust the spiciness as desired.
6. Serve: Once the meatballs are cooked, remove them from the oven and let them cool slightly. Serve warm with the spicy mayo dip on the side.
