A complete meal packed with savory flavor and essential nutrients. The flavor combination of green beans and mushrooms pair well together. Roasting vegetables seems to concentrate their flavors and make them even tastier. Farro is a really nice whole grain due to its earthy nuttiness and the chewy texture. For folks who are eating gluten-free, you can use brown rice instead or substitute for quinoa, amaranth or buckwheat. The balsamic vinaigrette and feta brighten this dish with the perfect acidity. An excellent vegetable side dish everyone is sure to love!
