Finely shred the green cabbage and thinly slice the red bell pepper into strips.
In a small bowl, whisk together the coconut aminos, sriracha, and red pepper flakes to create the stir-fry sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the ground turkey to the skillet, seasoning with sea salt and black pepper, and cook until browned and fully cooked through, breaking it into small crumbles.
Stir in the minced garlic and grated ginger, sautéing for about 1 minute until fragrant.
Add the sliced bell peppers and shredded cabbage to the skillet, tossing frequently for 3 to 5 minutes until the vegetables are tender-crisp.
Pour the sauce over the turkey and vegetable mixture, tossing well to coat everything evenly.
Continue to cook for another 1 to 2 minutes until the sauce has thickened slightly and the flavors are well combined.
Transfer the mixture to a bowl and serve immediately while hot.
