I couldn't believe how easy these were to make and how great they tasted. Just be careful your grill is not too hot or they will burn. If you are cooking them with a steak, I would wait until they are off the grill and resting before I put them on. They only take 10 minutes!
1 pound potatoes, preferably fingerling, cut lengthwise into 1/4-inch-thick slices (I used baby new red potatoes)
2 cups white vinegar
2 tablespoons extra-virgin olive oil
1 1/2 teaspoons coarse salt, plus more for sprinkling
1/4 teaspoon freshly ground pepper
Bring potatoes and vinegar to a boil in a medium saucepan (vinegar should cover potatoes). Reduce heat to medium-low, and simmer potatoes until just fork tender, about 5 minutes. Let potatoes cool in vinegar for 30 minutes. Drain well, and gently toss with oil, salt, and pepper.
Preheat grill to medium-high. Grill potatoes in a single layer until browned on both sides and cooked through, about 5 minutes per side. Sprinkle with salt before serving.
Yield: 4 servings
