Looking to spruce up your usual summer potato salad? By adding just a couple special ingredients or even changing the type of potato, you can bring that ordinary potato salad back to life. Here I used sweet potato to give this potato salad an unusual kick. The color combination of orange and black is more Halloween than Fourth of July, but to me this salad is all summer. The cinnamon gives it an earthy fall flavor, but the lime kicks it back into the sunny season we all love. I prefer it to regular potato salad because sweet potato can be more flavorful and dimensional, as well as healthier because of its fiber content.
