This recipe is for those who want to add some punch to an otherwise typical potato side dish.
In a small pot, combine the potato slices, vinegar, and water. Bring to a boil, then lower the heat and simmer until fork-tender, about 20 minutes. Let potatoes cool in liquid for 30 minutes. Then drain well and pat dry with paper towels.
Preheat broiler. Place the potato slices onto a cookie sheet, sprinkle very generously with olive oil, salt, and pepper, and toss to coat.
Arrange the potato slices in a single layer. Broil until lightly browned on top, about seven to eight minutes. Then flip the slices and broil until the underside is lightly browned, about seven to eight minutes more.
