Slice the chicken breast into thin, bite-sized strips and season with sea salt and black pepper.
Mince the garlic and grate the fresh ginger.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the pan and sear until golden brown and cooked through, about 5-6 minutes.
Remove the chicken from the pan and set aside.
Add the broccoli florets, sliced bell pepper, and snap peas to the same pan, sautéing for 3-4 minutes until tender-crisp.
Stir in the garlic and ginger, cooking for 30 seconds until fragrant.
Return the chicken to the pan and pour in the coconut aminos and toasted sesame oil.
Toss everything together for 1 minute to glaze the ingredients before serving.
