Dice the chicken breast into bite-sized pieces and peel and devein the shrimp.
Heat the avocado oil in a large skillet or griddle over medium-high heat until shimmering.
Add the diced zucchini, onions, and carrots to the pan, sautéing until they are tender-crisp and slightly charred.
Move the vegetables to the side of the pan and add the chicken, cooking until golden brown and cooked through.
Add the shrimp to the pan, searing for approximately 2 minutes per side until pink and opaque.
Push all ingredients to the edges of the pan, pour in the sesame oil, and crack the egg into the center, scrambling it quickly until set.
Stir in the cooked brown rice, coconut aminos, garlic powder, ginger powder, sea salt, and black pepper.
Toss all ingredients together for 2 minutes to allow the flavors to meld and the rice to become slightly crispy before serving.
