Punch up potato salad with a savory dressing instead of the same old mayo. Add poached shrimp and you've got an elegant appetizer.

Green goddess dressing:

4 anchovy fillets, chopped
2 green onions, green parts only, finely chopped
1½ tablespoons chopped parsley
2 tablespoons chopped tarragon
2 tablespoons tarragon vinegar
2 tablespoons minced chives
1½ cups mayonnaise
