Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the ground chicken to the skillet, seasoning with sea salt and black pepper, and cook while breaking it apart until fully browned.
Stir in the minced garlic and fresh ginger, sautéing for about 1 minute until the aromatics are fragrant.
Add the broccoli florets, sliced bell peppers, and snap peas to the pan, tossing frequently for 4-5 minutes until the vegetables are tender-crisp.
In a small bowl, whisk together the coconut aminos, rice vinegar, and toasted sesame oil.
Pour the sauce over the chicken and vegetable mixture, stirring for 1-2 minutes until everything is well-coated and heated through.
Remove from heat, garnish with sesame seeds, and serve immediately.
