Dice the chicken breast into small, bite-sized pieces and finely chop the broccoli and carrots.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the pan and cook for 5-6 minutes until golden brown and cooked through, then remove and set aside.
In the same pan, add the broccoli, carrots, minced garlic, and grated ginger, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Push the vegetables to one side of the pan, crack the egg into the empty space, and scramble until fully set.
Add the cooked brown rice, frozen peas, and cooked chicken back into the pan.
Drizzle the tamari and toasted sesame oil over the mixture, tossing everything together for 2 minutes to heat through and develop a slight char on the rice.
Garnish with thinly sliced green onions and serve immediately.
