Slice the chicken breast into thin, bite-sized strips and season evenly with sea salt and black pepper.
Wash the baby bok choy thoroughly, then slice the white stems into 1-inch pieces and roughly chop the green leaves.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the chicken strips to the skillet and sear for 4-5 minutes until golden brown and cooked through, then remove and set aside.
In the same skillet, add the minced garlic and grated ginger, sautéing for 30 seconds until the aroma is released.
Add the sliced carrots and red bell pepper to the pan, stir-frying for 2 minutes until they begin to soften.
Toss in the bok choy stems and cook for another 2 minutes, then add the green leaves and stir until just wilted.
Return the cooked chicken to the skillet and pour in the coconut aminos, rice vinegar, and toasted sesame oil.
Toss all ingredients together for 1 minute to coat thoroughly in the glaze, then serve immediately garnished with sesame seeds.
