Blanch carrots in boiling water. (I prefer my carrots to be soft, therefore I will boil them longer till they turn tender.) Dish and drain.
Heat up oil, stir fry mushrooms and scallops until fragrant. Add seasoning and bring to boil.
Add in blanched carrots and other veges (if using) and the remaining ingredients (prawns, crabsticks, etc) and simmer for 3-4 minutes.
Dish up and serve hot.
