Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the ground chicken, sea salt, and black pepper to the pan, breaking the meat into small crumbles with a spatula.
Cook the chicken undisturbed for 3-4 minutes to develop a golden, crispy crust before stirring.
Add the minced garlic and grated ginger to the skillet, sautéing for 60 seconds until the aromatics are fragrant.
Toss in the chopped bok choy and sliced red bell peppers, cooking for 2-3 minutes until the vegetables are tender-crisp.
In a small bowl, whisk together the coconut aminos, toasted sesame oil, and red chili flakes.
Pour the sauce over the chicken and vegetable mixture, tossing constantly for 1 minute to coat everything in a glossy glaze.
Remove from heat and garnish with thinly sliced green onions before serving.
