How to Make It
Whisk together oyster sauce, soy sauce, sesame oil, fish sauce, and sugar in a bowl.
Heat coconut oil in a wok. Add the onion, scallions, garlic, and peppercorns; stir-fry over high until onions are crisp-tender, about 2 minutes. Working in 2 batches, stir-fry the squid and chiles for 2 minutes. Add the sauce mixture and stir-fry until thickened, about 7 minutes. Season with salt, and serve with rice.
