In a small bowl, whisk together the gochujang, tamari, raw honey, grated ginger, and minced garlic until smooth.
Cut the chicken breast into bite-sized cubes 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 skillet and sear for 5-6 minutes, stirring occasionally, until golden brown and cooked through.
Remove the chicken from the pan and set aside; add the broccoli, sliced bell peppers, and snap peas to the same pan with a tablespoon of water.
Cover and steam-fry the vegetables for 3 minutes until they are vibrant and tender-crisp.
Return the chicken to the pan and pour the prepared gochujang sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce has thickened and creates a glossy glaze.
Remove from heat, drizzle with toasted sesame oil, and garnish with sesame seeds and sliced green onions before serving.
