Slice the chicken breast into thin, bite-sized strips and season evenly with sea salt and black pepper.
Mince the garlic clove and finely grate the fresh ginger.
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 hot pan and sear for 4-5 minutes, stirring occasionally, until golden brown and cooked through.
Remove the chicken from the pan and set it aside on a plate.
In the same skillet, add the broccoli florets, sliced bell peppers, and sugar snap peas, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Stir in the minced garlic and grated ginger, cooking for about 30 seconds until highly fragrant.
Return the cooked chicken to the pan and pour in the coconut aminos and toasted sesame oil.
Toss all ingredients together for 1 minute to ensure everything is well-coated and heated through, then serve immediately.
