Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
In a medium mixing bowl, combine the ground turkey, grated fresh ginger, minced garlic, sea salt, and black pepper, mixing gently with your hands until just incorporated.
Form the turkey mixture into 12 small, uniform meatballs and place them on the prepared baking sheet.
Bake for 15 to 18 minutes until the meatballs are cooked through and reach an internal temperature of 165°F.
Remove the meatballs from the oven and let them cool completely, then place them in the refrigerator for at least 20 minutes to chill.
In a large serving bowl, assemble the base by layering the shredded purple cabbage, sliced cucumber, grated carrots, and shelled edamame.
In a small glass jar or bowl, whisk together the tamari and toasted sesame oil until emulsified, then drizzle it evenly over the vegetables.
Top the veggie bed with the chilled turkey meatballs and garnish with sliced green onions and sesame seeds before serving.
