Split peas. So simple, so inexpensive, so good for you. A member of the legume family, split peas are a really great source of fiber: which helps lower cholesterol and maintains even blood sugar balance. They are also a good source of protein and have potassium and B vitamins.
This recipe has some smoked ham in it, which does add a rich smoky flavor. But feel free to sub in onions and fennel instead for increased vegetable flavor.
