Slice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
In a small bowl, whisk together the gochujang, coconut aminos, toasted sesame oil, minced ginger, and minced garlic to create the glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sear until golden and cooked through, approximately 5-6 minutes, then remove and set aside.
Add the broccoli, bell pepper, and snap peas to the same skillet, sautéing for 3-4 minutes until they are tender-crisp and bright.
Return the cooked chicken to the pan and pour the gochujang glaze over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and coats the ingredients beautifully.
Garnish with sesame seeds and serve immediately.
