I enjoy cabbage but rainbow chard takes it to another level! Swiss chard is great for making rolls and wraps. It is also a nutritional powerhouse full of vitamins and more. Chard even has 16% more iron than kale. Experiment with your roll by using couscous, quinoa, or different veggies and herbs. They can be filled with almost anything! How about a side of pita bread? Serves 4.
