In a small bowl, whisk together the coconut aminos, minced ginger, minced garlic, arrowroot starch, and water to create the stir-fry sauce.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the ground chicken to the skillet, seasoning with the sea salt and black pepper.
Cook the chicken, breaking it up with a spatula, until it is golden brown and fully cooked through.
Add the broccoli florets to the pan along with a tablespoon of water; cover with a lid for 2 minutes to lightly steam the broccoli until it is vibrant green.
Remove the lid and pour the prepared sauce over the chicken and broccoli.
Stir-fry for 1 to 2 minutes until the sauce thickens into a glossy glaze that coats every piece.
Garnish with sliced green onions and serve immediately.
