Rinse the rice thoroughly under cold water until the water runs clear.
Add the rinsed rice to the bottom of your rice cooker pot.
Layer the ingredients on top of the rice (do not mix).
Add the sliced chicken breasts, onions, garlic, and black peppercorns.
Pour in the soy sauce, sweet soy sauce, vinegar, and honey over the top.
Gently pour in the chicken stock or water. Place the bay leaves on top.
Cook using the regular rice setting. Let the rice cooker run its full cycle.
Once done, let it sit for 5–10 minutes.
Remove the bay leaves and gently fluff the rice to mix everything together.
Serve hot, optionally garnished with green onions or a drizzle of sauce from the bottom of the pot.
