Heat the extra virgin olive oil in a large skillet or wok over medium-high heat.
Add the diced chicken breast, sea salt, and black pepper, sautéing until the chicken is golden and cooked through.
Remove the chicken from the pan and set it aside on a plate.
In the same pan, add the diced carrots and chopped broccoli, cooking for 3-4 minutes until they are tender-crisp.
Stir in the minced garlic and grated fresh ginger, cooking for 30 seconds until the mixture is highly aromatic.
Push the vegetables to one side of the pan, crack the egg into the empty space, and scramble it until fully set.
Add the chilled cooked brown rice, frozen peas, the prepared chicken, and tamari to the pan.
Drizzle with toasted sesame oil and toss all ingredients together for 2 minutes to ensure everything is heated through and well-combined.
Garnish with sliced green onions and serve immediately while hot.
