Season the sliced chicken breast strips with sea salt and black pepper.
In a small bowl, whisk together the tamari, rice vinegar, toasted sesame oil, and red pepper flakes to create the sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the chicken strips to the skillet and cook until golden brown and cooked through, approximately 5 to 6 minutes.
Remove the chicken from the skillet and set it aside on a plate.
In the same skillet, add the minced ginger and garlic, sautéing for about 30 seconds until fragrant.
Add the shredded cabbage and julienned carrots to the skillet, stir-frying for 3 to 4 minutes until they are tender-crisp.
Return the cooked chicken to the skillet and pour the prepared sauce over the mixture.
Toss all ingredients together for 1 minute until everything is well coated and heated through.
Garnish with sliced green onions and serve immediately.
