Beat eggs and fish sauce together, heat a wok and drizzle with sesame oil. Add the eggs and turn over the cooked egg-the raw stuff will flood to the outside. Keep cooking until you basically have an omellete shape of just cooked egg. Remove from the wok and set aside.
Heat wok to hot, and add the tablespoon of sesame and the tablespoon of vegetable oil.Add the garlic and cook sir frying until opaque-don't burn it. Add the rice and toss over a high heat for a few minutes, then add the egg omlette breaking it up gently as you toss it through the rice. When the whole lot is hot, add the oyster sauce, toss through and serve.
