These appetizers call for purchased chicken salad and croissants. All that it requires is a bit of assembly.
In a very large bowl stir together the chicken salad and the tarragon or mint. Fill each split croissant with about 1/4 cup chicken salad mixture. Layer filled croissants in a large roasting pan; cover and chill up to 4 hours. To serve, arrange on serving platters. Makes 50 croissants.
