Oven roasted potatoes give this potato salad unique flavor and texture. The potatoes are dressed with a simple, savory mixture of mayonnaise, sour cream, and lemon juice. Dill, red onion, chives, and garlic provide color and flavor. It's easy to make, especially if you do not peel the potatoes. There is no need to do so as the skins will add nutrition and extra flavor to the potato salad. This potato salad will be the hit of the cookout or potluck, and it goes well with grilled meat, chicken, or burgers. Add a little diced cooked bacon to this potato salad for extra flavor.
