Shiitake is one of the most popular vegetarian substitutes for meat. Apart from being a good source of iron and protein, it's chock-full of rich umami flavor. You can simply sauté them and they'd already taste incredibly delicious. What more if you do something more with them? They're perfect for pastas, salads, and more! You can also stuff them with pork to enhance its flavor even further. Feel free to check out this collection of shiitake mushroom recipes to learn more.
