To make pickled onions, in small saucepan, bring 2 cups water to boil. Add onions; simmer thirty seconds. Drain and place onions in small bowl. Add vinegar and enough water to barely cover. Refrigerate, covered, at least one hour or up to 2 weeks. In 3-quart saucepan, bring 1 quart water to boil. Add potatoes and 1 teaspoon salt; cook, covered, 10 to 12 minutes until just tender. Drain and cool. Meanwhile, in large bowl, mix lime juice, vinegar, sugar, hot sauce and black pepper; whisk in oil. Add potatoes and remaining ingredients except pickled onions. Toss gently. Season with salt to taste. Mound salad in bowl or on four serving plates. Garnish with drained pickled onions. |
