Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Season the diced chicken breast with sea salt and black pepper, then add it to the pan and sear until golden and cooked through.
Push the chicken to one side of the skillet and crack the egg into the empty space, scrambling it until fully set.
Add the diced carrots, frozen peas, minced garlic, and grated ginger to the pan, sautéing for 2-3 minutes until the vegetables are tender-crisp.
Stir in the cauliflower rice and cook for an additional 3-4 minutes, allowing it to soften slightly while maintaining a firm texture.
Drizzle the coconut aminos, rice vinegar, and toasted sesame oil over the mixture, tossing everything together to coat evenly.
Remove from heat and garnish with thinly sliced green onions before serving warm.
