Another dish from my Mom's birthday. We had a seafood party. Rub the fish with salt, let it stay for a while and rinse. Steam the Lapu-Lapu until cooked. For the sauce, just mix oyster sauce, soy sauce, some water, sugar, ginger, a small onion, onion leeks, chives leaves, minced garlic and sesame oil and cook it for a while. Pour over the steamed Lapu-Lapu. Simple and yummy.
