I use my little rice cooker to do steaming, it came with a steamer basket and works perfect for items like this. Three chicken breasts was just a bit over 500 grams, perfect, no one will complain.
Steam the chicken breasts for 20-25 minutes or until cooked through, cut one in half to check doneness.
When cooked, remove from the steamer and allow to cool, then shred and place in a large mixing bowl.
Heat the oil in a non stick pan on medium heat, when hot, add the garlic and red pepper flakes. Stir fry until fragrant, about 1-2 minutes. Remove from heat.
To the pan, stir in the salt, oyster sauce, soy sauce, and cumin.
Add the cilantro, reserving a small amount for garnish) to the chicken in the mixing bowl and toss to mix that in.
I did use a variant and added some diced pickled red onion.
Add the garlic mixture from the pan and toss to mix well.
Serve and garnish with cilantro or chill and serve with cilantro garnish.
