Dice the chicken breast into small, uniform bite-sized pieces and finely mince the garlic and fresh ginger.
Heat the avocado oil in a large skillet or wok over medium-high heat until the oil is shimmering and hot.
Add the diced chicken to the pan and season with sea salt and black pepper, sautéing until the exterior is golden brown and the meat is cooked through.
Stir in the diced carrots, minced ginger, and garlic, cooking for 3 minutes until the vegetables soften and the aromatics become fragrant.
Push the chicken and vegetable mixture to the outer edges of the pan and pour the sesame oil into the center.
Add the chilled jasmine rice directly onto the sesame oil, pressing it down firmly with a flat spatula for 2 minutes to allow the bottom to develop a crispy, toasted crust.
Toss all ingredients together, then stir in the frozen peas and tamari, cooking for an additional 2 minutes until the peas are bright green and the sauce is well-distributed.
Remove the pan from the heat and garnish the dish with thinly sliced green onions before serving immediately.
