Place all ingredients for the meatballs in a large bowl. Mix until just combined.
1 lb ground beef, 1/2 cup minced green onions, 4 garlic cloves, 1 inch ginger, 2 tbsp tamari sauce, 1-2 tsp gochujang, 2 tbsp cornstarch, 1 tsp ground black pepper
Use a two tablespoon scoop (or a rounded tablespoon) to roll into golf-sized meatballs -- about 20 meatballs. Place in the fridge for about 10 minutes.
Heat sesame oil in a large skillet with a lid over medium high heat. Add garlic and cook for 1 minute until fragrant.
1 tbsp sesame oil, 4 garlic cloves
Add tamari sauce, water, brown sugar, and rice vinegar and stir.
1/3 cup tamari sauce, 1 cup water, 3 tbsp brown sugar, 2 tbsp rice vinegar
Add the meatballs into the skillet. Let everything come to a boil, then lower to simmer. Cover and cook for 10 minutes.
Combine cornstarch and water in a small bowl, and stir to combine.
2 tsp cornstarch, 1 tbsp water
Remove the lid and add the cornstarch slurry. Stir then simmer for another 5-10 minutes until the sauce reduces and thickens to your liking, spooning the sauce over the meatballs occasionally.
Taste to add more tamari sauce, if needed. Remove from heat, then serve over rice. Garnish with green onions and sesame seeds.
