Preparation time: 25 minutes.
Cooking time: 25 minutes.
Set broiler rack about 6 inches from heat. Turn on broiler.
Toss potatoes and fennel in 1/4 cup olive oil; reserve any extra oil. Spread in single layer on broiler pan. Lightly season with salt and pepper. Broil until blistered and slightly blackened, turning once, about 5 minutes per side. Bake in 400-degree oven until just tender, about 15-20 minutes. Do not overcook potatoes.
When cool enough to handle, cut potatoes and fennel into 1/2-inch dice. Toss with all oil, 6 tablespoons vinegar and remaining ingredients. Season to taste. Add remaining tablespoon vinegar if needed. Can be made several hours ahead and kept at room temperature or a day ahead and refrigerated, covered airtight. Let come to room temperature before serving. Adjust seasoning.
'This salad would be a great accompaniment to any grilled meat or poultry. Try to make it several hours or a day ahead so the flavors have a chance to deepen and meld together.'
