Quinoa & Veggie Stuffed Portabellas


Mushrooms are often used in vegetarian dishes because they bring umami or earthy, meaty flavor, but without the meat. While mushrooms like portabellas are loaded with nutrients, they are not a good source ofplant-based protein. These portabellas are stuffed with quinoa, a grain that is actually a seed, to boost their protein content for a more balanced and satisfying meal. Enjoy these Quinoa & Veggie Stuffed Portabellas with tomato sauce or pesto and a sprinkle of Parmesan cheese.
