Acacia Omelette (kai jeaw cha-om) : this recipe is optional. However, thai people love to eat this omelette with hot and sour curry. (If you cannot find acacia in your local grocery store, you may try to use other fresh vegetables instead.)

2. Add the beaten eggs in a bowl, and also add the acacia. Stir until all mixed well.
3. Heat oil in a wok. Add the beaten eggs with acacia in the wok, fry until cooked and golden, then remove and drain. Slice into cubes.
