Add all of the ingredients for the stir fry sauce to a small blender, such as a Magic Bullet, and blend until well-combined. If you don’t own a small blender, use a small bowl and whisk the ingredients well. Set aside until ready to use.
Heat the avocado oil in a large nonstick skillet or a wok over high heat. Add the onion and sauté, stirring often, until it begins turning golden-brown around the edges.
Add the chopped chicken and minced garlic and stir well. Cook, stirring occasionally, until chicken has browned but is not quite cooked through. If at any point the ingredients appear to be cooking too quickly, reduce the stove top to medium heat.
Transfer the chopped broccoli florets and bell pepper to the skillet, followed by the stir-fry sauce. Stir well and cook, stirring occasionally, until the sauce has thickened and the broccoli has reached your preferred level of doneness. Taste the stir fry for flavor and add sea salt and black pepper to your personal taste.
Serve chicken and broccoli stir fry with steamed brown rice, white rice, or cauliflower rice with a sprinkle of sesame seeds and chopped green onions. If you love cilantro, add some chopped cilantro or Thai basil on top just before serving.
