Dice chicken into small bite-sized pieces and season with sea salt and black pepper.
Heat avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add chicken to the pan and cook until golden brown and cooked through, about 5-6 minutes.
Remove chicken from the pan and set aside.
In the same pan, add sesame oil, minced garlic, grated ginger, and diced carrots, sautéing until carrots are slightly tender.
Increase heat to high and add the chilled rice, spreading it out to let it develop a crispy texture for 2 minutes.
Stir in the peas, cooked chicken, and tamari, tossing everything together until heated through.
Garnish with sliced green onions and serve immediately.
