Pat the chicken breast dry with paper towels and season evenly with sea salt and black pepper.
Heat the avocado oil in a large stainless steel or cast iron skillet over medium-high heat until it begins to shimmer.
Add the chicken to the skillet in a single layer and cook undisturbed for 3 minutes to develop a golden crust.
Flip the chicken and cook for another 2-3 minutes until completely cooked through, then remove from the pan and set aside.
Lower the heat to medium and add the sesame oil to the same skillet along with the diced carrots and frozen peas.
Sauté the vegetables for 3-4 minutes until the carrots are tender and the peas are bright green.
Stir in the minced garlic and grated fresh ginger, cooking for just 30 seconds until the aromatics are fragrant.
Add the cooked brown rice to the skillet, spreading it out and pressing down firmly to allow the bottom to crisp for 2 minutes.
In a small bowl, whisk together the tamari and honey, then drizzle the mixture over the rice and stir to combine.
Return the cooked chicken to the pan, toss with the green onions and sesame seeds, and serve immediately while hot.
