Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the ground chicken to the skillet, seasoning with sea salt and black pepper.
Cook the chicken for 5-7 minutes, breaking it into small crumbles with a spatula, until browned and cooked through.
Add the broccoli florets, sliced red bell pepper, and shredded carrots to the pan.
Stir-fry the vegetables with the chicken for 4-5 minutes until the broccoli is tender-crisp and bright green.
In a small bowl, whisk together the tamari, toasted sesame oil, grated ginger, and minced garlic.
Pour the sauce over the chicken and vegetable mixture, tossing constantly for 1 minute to coat everything evenly.
Remove from heat and garnish with thinly sliced green onions before serving.
