1. Whisk the eggs with the fish sauce, then stir in the ground pork, shallots, garlic and minced coriander leaves, mixing well.
2. You can use a small skillet to make individual omelets. Put about 1/2 teaspoon of oil in a small skillet. When moderately hot, pour in 1/4 of the egg mixture and cook until the edges are starting to set, about 1 minute
3. Lift the edges of the omelet with a spatula and let the liquid portion of egg run underneath. Cook until the bottom of the omelet is golden brown and the top almost set, 1 to 2 minutes. Slide the omelet out onto a plate, then flip it over into the pan and continue cooking until the other side is golden brown, about another 2 minutes.
4. Put the omelet on a plate and continue cook- ing, adding a little oil to grease the pan each time, to make four omelets. Arrange the omelets on a serving plate and garnish each with a sprig of coriander leaves if desired. Serve at room temperature accompanied by the dip
