Heat avocado oil in a large skillet over medium-high heat until it shimmers.
Add ground chicken and cook, breaking it into small crumbles with a spatula, until no longer pink and slightly browned.
Stir in the minced garlic and grated ginger, cooking for 1 minute until highly aromatic.
Toss in the broccoli florets and red bell pepper slices, stirring to combine with the chicken and aromatics.
Pour in the coconut aminos, sea salt, and black pepper, then cover the pan to steam the vegetables for 3 minutes.
Remove the lid and stir in the toasted sesame oil, allowing the flavors to meld for 1 minute.
Prepare the cauliflower rice by lightly steaming it in a separate pan until just tender.
Divide the cauliflower rice into bowls, top with the chicken stir-fry, and garnish with sesame seeds and sliced green onions.
