Slice the chicken breast into 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 the oil is shimmering.
Add the chicken to the pan and sear until golden brown and cooked through, approximately 5 to 6 minutes.
Remove the chicken from the skillet and set aside on a plate, then add the broccoli, bell pepper, and snap peas to the same pan.
Stir-fry the vegetables for 3 to 4 minutes until they are bright green and tender-crisp.
Stir in the minced garlic and grated ginger, cooking for 30 seconds until the mixture becomes highly fragrant.
Return the cooked chicken to the pan and drizzle with the coconut aminos and toasted sesame oil.
Toss all ingredients together for 1 minute to ensure everything is thoroughly coated in the savory glaze.
Transfer to a bowl and garnish with sesame seeds before serving hot.
