Warm Potato Salad with Goat Cheese

1 tablespoon white wine vinegar or sherry vinegar
1 tablespoon freshly squeezed lemon juice
Salt to taste
1 teaspoon Dijon mustard
1 small or medium clove garlic, minced or pureed
1/3 cup olive oil — for low-fat dressing, use 1/4 cup yogurt or buttermilk and 2 tablespoons olive oil

Whisk together the vinegar, lemon juice, salt, mustard and garlic. Whisk in the olive oil. Taste and adjust seasonings. You can make it several hours in advance.

1 1/2 pounds fingerling potatoes, washed
Salt and fresh ground pepper to taste
3 tablespoons finely chopped red onion, rinsed with cold water and drained
2 tablespoons chopped Italian parsley
2 ounces soft goat cheese
2-3 sage leaves, cut into thin slivers (optional)

Cut the potatoes into 3/4-inch slices. Steam above 1 inch of boiling water until tender but not mushy, about 10-12 minutes. Remove from heat and while still hot, toss in a bowl with salt and pepper, red onion, parsley, goat cheese and the dressing. Sprinkle the sage over the top and serve.
