Hello Uzma, yes, the bay leaf and whole spices are removed before filling the pastry sheet. Please add 1/2 cup of boiled peas to the chicken mix.

You sure can! The cooked puff pastry appetizer freezes perfectly. Let them cool completely, and then wrap them in wax paper. Place them on the baking tray and freeze until solid. Once frozen, transfer them to a zip-lock bag and slide them into the freezer.
They stay good for 2 months! When ready to serve, take them out from the freezer and reheat/bake them at 400° F (200° C) until golden brown and crispy.

Sadhana, you can make the filling a day in advance and store it. Wrap and bake the puffs for that flaky texture on the day of serving. Because if wrapped and stored uncooked, then the oil and liquids from the filling may make the puff pastry sheets soggy.
