Kale and Roasted Vegetable Soup Recipe | Simply Recipes

Modify this by cubing the butternut squash in advance and then roasting time can be cut in half and you don't get shriveled carrots like I did...also, I didn't cook the kale as long as it said to. I didn't want to cook out all the goodness of the veggies! I didn't use half as much oil as it said, either, and didn't use any added salt. In other words, use common sense to make this healthier. It's already pretty healthy, so imagine how great it can be :)
