Slice the chicken breast into thin, bite-sized strips and season evenly with sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 5 to 6 minutes.
Remove the chicken from the pan and set aside on a plate to keep warm.
In the same skillet, add the broccoli florets, sliced bell pepper, and snap peas, sautéing for 3 to 4 minutes until they are tender-crisp.
Stir in the minced garlic and grated ginger, cooking for about 30 seconds until the aromatics are 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.
Serve the stir-fry immediately over a bed of steamed cauliflower rice for a clean, low-carb finish.
