Heat the sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the diced chicken breast, seasoning with sea salt and black pepper, and sauté until the chicken is golden brown and cooked through.
Remove the chicken from the pan and set it aside on a plate.
In the same pan, add the minced garlic and sauté for 30 seconds until fragrant and lightly toasted.
Add the chilled jasmine rice to the pan, breaking up any clumps with a spatula to coat the grains in the garlic oil.
In a small bowl, whisk the eggs and pour them directly over the rice, stirring constantly so the eggs coat the rice and cook into fluffy golden bits.
Fold the cooked chicken, frozen peas, and tamari into the rice mixture, tossing until everything is well combined and heated through.
Garnish with thinly sliced green onions and serve immediately.
