Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the cubed eggplant and sea salt to the skillet, sautéing for 6-8 minutes until the eggplant is soft and golden brown.
Push the eggplant to the outer edges of the pan and add the ground turkey to the center, breaking it apart with a wooden spoon.
Cook the turkey until it is fully browned and no longer pink, then mix it together with the eggplant.
Add the minced garlic, grated ginger, and red pepper flakes, stirring constantly for 60 seconds until highly fragrant.
In a small bowl, whisk together the tamari, rice vinegar, and toasted sesame oil, then pour the mixture over the stir-fry.
Toss everything together for 2 minutes until the sauce has thickened slightly and glazed the turkey and eggplant.
Remove from heat, season with black pepper, and garnish with sliced green onions before serving.
