In a small bowl, whisk together the gochujang, tamari, toasted sesame oil, and raw honey until the sauce is smooth.
Slice the chicken breast into bite-sized pieces and mince the garlic and fresh ginger.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and cook until golden brown and cooked through, then remove the chicken and set it aside.
In the same skillet, add the broccoli florets and sliced red bell pepper, sautéing for 3-4 minutes until they are tender yet remain crisp.
Return the chicken to the skillet, add the minced garlic and ginger, and cook for 1 minute until fragrant.
Pour the gochujang sauce over the mixture and toss well for 1-2 minutes to coat everything in the thick, spicy glaze.
Garnish with sliced green onions and sesame seeds before serving hot.
