Dice the chicken breast into small, uniform pieces and season with sea salt, black pepper, garlic powder, and ground ginger.
Heat a large skillet or wok over medium-high heat and add half of the toasted sesame oil.
Add the seasoned chicken to the skillet and sauté until golden brown and cooked through, then remove from the pan and set aside.
Add the remaining sesame oil to the same skillet and toss in the finely chopped broccoli and diced carrots, sautéing for 3-4 minutes until tender-crisp.
Push the vegetables to the side of the pan, pour in the whisked egg, and scramble until just set before mixing with the vegetables.
Stir in the cooked jasmine rice, green peas, and tamari, tossing constantly for 2 minutes to allow the rice to slightly crisp and absorb the flavors.
Return the cooked chicken to the pan, folding it into the rice mixture until heated through.
Garnish with sliced green onions and sesame seeds before serving hot.
