No need to peel this squash- once cooked, delicata squash has an edible, tender skin. To prepare, cut off the ends, slice lengthwise and remove the seeds with a melon baller. Roasting the squash, cauliflower and red onion caramelizes the natural sugars for a rich flavor. Remember to successfully roast vegetables, cut them into similar sized pieces, so they cook evenly. This nutrient-dense dish provides dietary fiber, vitamin A and vitamin C.
