One of the most underappreciated leaves in the green community, yet a celebrity if you're into the raw food movement. This Southern leaf has a thick, chewy texture that makes a great substitute for bread. Because of its fiber-rich construction, collard greens are a great preventative to constipation as well as hemorrhoids and colon cancer. Think of collard greens as the pre-disease vegetable: it is, after all, in the same family as kale.
How to enjoy: Although collard greens are typically slow-cooked in Southern recipes, you can use them in various other ways. One way is to turn your salad into a wrap by enclosing all of the ingredients you would typically put on your bed of lettuce. By eating the leaves raw, you are avoiding what can also be a potentially stinky situation.
