Pretty easy to put together. Since this recipe has an Asian flair, I used reconstituted Shitake instead of fresh sliced button mushrooms. I also substituted a hefty teaspoon of Indonesian hot pepper condiment (Sambal Oelek) in place of the pepper flakes. My wife usually is critical of me trying out new recipes, but she loved this one. I would have to say that the pineapple swayed her taste buds. This is a tasty soup!
