Heat the avocado oil in a large cast-iron skillet or wok over medium-high heat until shimmering.
Add the ground chicken to the skillet, spreading it into an even layer. Season with sea salt and black pepper.
Allow the chicken to cook undisturbed for 4-5 minutes until the bottom develops a deep golden-brown crust.
Flip the chicken and break it into small crumbles using a wooden spoon or spatula.
Add the broccoli florets and sliced red bell pepper to the skillet, stirring frequently for 3-4 minutes until the vegetables are tender-crisp.
In a small bowl, whisk together the coconut aminos, toasted sesame oil, garlic powder, and ginger powder.
Pour the sauce over the chicken and vegetable mixture, tossing constantly for 1 minute until everything is well-coated and fragrant.
Remove from heat and garnish with sesame seeds before serving.
