These chicken and olive pastries make great appetizers that you can impress your guests. Make them ahead of time or have them ready in 45 minutes.
Use 2 cups chopped cooked rotisserie chicken from the deli instead of the frozen chicken.
The filling can be made up to 2 days ahead of time; cover and refrigerate.
For a festive touch, cut leftover pastry with a miniature star- or snowflake-shaped cutter and place cutouts on top of filling in cups before baking.
