Creating Korean BBQ Meatballs with Spicy Mayo Dip can be a fun and rewarding process. Follow these simple steps:

1. Prepare the Meatball Mixture: In a large mixing bowl, combine ground beef, breadcrumbs, green onions, garlic, ginger, soy sauce, sesame oil, brown sugar, black pepper, and the beaten egg. Mix until all ingredients are well incorporated.

2. Form Meatballs: Using your hands, shape the mixture into meatballs, about 1 inch in diameter. You should have approximately 20 meatballs.

3. Preheat Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easier cleanup.

4. Bake Meatballs: Place the meatballs on the prepared baking sheet. Bake for 15-20 minutes, or until they are browned and cooked through.

5. Prepare Spicy Mayo Dip: While the meatballs are baking, in a small bowl, whisk together mayonnaise, gochujang, lemon juice, honey, and garlic powder until smooth. Adjust the spice level to your preference by adding more gochujang if desired.

6. Check Meatball Doneness: To ensure the meatballs are fully cooked, check that the internal temperature reaches 160°F (71°C).

7. Make Final Touches: Once the meatballs are done, remove them from the oven and let them cool slightly before serving.

8. Serve with Dip: Transfer the meatballs to a serving platter alongside the spicy mayo dip for guests to enjoy.
