Dried shiitake mushroom is a good source of fiber. It stores well because it's dried, which if the green vegetable is running out of stock, this mushroom can be used as a fiber savor. I soaked some last night and use it to stir fried with rice. Also, I soaked some dried scallop in wine and added them in to give more in depth flavor. The rice is also flavored with garlic and soy sauce, with some tomato added at last. Very delicious! The bowl holds the rice the another new gift from the holiday. Love it!
