1/2 Tbsp. white wine vinegar
1/3 c. Greek plain yogurt
1 Tbsp. extra virgin olive oil
3/4 Tbsp. fresh lemon juice
1 medium shallot, finely chopped about 1/4 cup
1-1/2 Tbsp. minced fresh dill
6 large radishes, thinly sliced with a mandolin
We cooked the potatoes the way we normally do by steaming them in microwave until they are tender but not mushy. Arrange them in a single layer and drizzle with vinegar and let cool.
In a glass bowl whisk together the yogurt, oil, lemon juice, shallots, half of the dill, 1 tsp. salt and pepper to taste.
Scrape the pototoes into a bowl with the yogurt dressing and fold in the radishes. Adjust the seasonings. Sprinkle with the remaining dill. Serve room temperature.
