Potato Salad with Yogurt and Dill

Potato salad is a classic summer picnic dish, but it's loaded with fat and calories. Here's a lightened version that's equally delicious. The secret is to substitute fat-laden mayonnaise with creamy nonfat-Greek yogurt, which also adds a pleasing tang. Add some mustard, lemon and some dill, and you have a great alternative to regular potato salad, with a fraction of the calories, and almost no fat.
