The zesty flavour of fresh ginger brings out the best in this simple, super-healthy, wonderfully low-fat, sweet potato and carrot mash. This is my adaptation of a recipe I found originally on one of my International Masters 'Good for You' recipe cards, which focus on health and nutrition. I use my Recipe #135453 when making this as I know that it is low in salt! I often add sunflower seeds to recipes such as this one and have included them here as an optional ingredient. They provide added nutrition and I just love the textural variation provided by that little bit of crunch! Walnuts would also work well. And yes, I know butter is not exactly healthy, but I do prefer to use it in cooking, so when I've made this recipe, I must confess that I've used butter. If you love sweet potatoes, you may also like my Recipe #124938, also very healthy but quite different from this recipe.
