Collard Greens are quite similar to other fibrous greens, like spinach, Swiss chard, and kale. Kale tends to have greater amount of nutrients within it per serving, but collard greens may be a better option if you have health restrictions on how much you can absorb - vitamin K being a perfect example. Spinach tells the same story, in that it has more nutrient content per serving, but spinach has less fiber. It shouldn't surprise you that Swiss chard is also similar to both kale and spinach, but Swiss chard has considerably more sodium in it per serving, so collard greens will be your best bet if you're looking to cut back on your salt intake. Whatever you decide to do is entirely up to you. This recipe we have for you below keeps things simple - that way you have the power to use it as a side if you have a much bigger meal in mind.
