Heat a large skillet or wok over medium-high heat until very hot.
Add the ground turkey, sea salt, and black pepper to the pan, breaking the meat into small crumbles with a spatula until browned and fully cooked.
Remove the cooked turkey from the pan and set it aside on a plate.
Lower the heat slightly to medium and add the toasted sesame oil to the same pan.
Sauté the diced onion, carrots, and frozen peas for 3-4 minutes until the vegetables are tender-crisp.
Stir in the minced garlic and fresh ginger, cooking for about 30 seconds until the aromatics become fragrant.
Push the vegetable mixture to the outer edges of the pan and crack the egg into the center, scrambling it quickly until just set.
Add the cooked brown rice and the reserved turkey back into the pan with the vegetables and egg.
Pour the tamari over the mixture and toss everything together for 2 minutes, allowing the rice to get slightly crispy and the flavors to meld.
Remove from heat and garnish with thinly sliced green onions before serving.
