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 shimmering.
Add the chicken to the pan and sear until golden brown and cooked through, about 5-6 minutes, then remove from the pan and set aside.
In the same pan, add the broccoli florets, sliced bell peppers, and sugar snap peas, sautéing for 3-4 minutes until tender-crisp.
Stir in the minced garlic and grated fresh ginger, cooking for 30 seconds until the aroma is released.
Return the cooked chicken to the skillet 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.
Steam the cauliflower rice in a separate small pan or microwave until tender.
Serve the hot chicken and vegetable mixture over the bed of cauliflower rice.
