When the oil is hot, pour 1/3 cup of the egg mixture into the pan. Fry in batches, flipping once, until they are puffed and brown, 1 1/2 to 2 minutes for each side. Transfer to paper towels to drain. Keep cooking in batches until all of the mixture is used up, add oil if needed.
Serve alone or with rice. Pour a generous amount of sauce over all and sprinkle with scallions
