Store-bought frozen puff pastry is a lifesaver any time of year, but especially as we move into the busy holiday season. With a package or two stashed in the freezer, I know a quick baked brie for visiting guests or plate of mini-quiche appetizers for a potluck is only a few steps away — and the empty, crumb-filled plates at the end of the night speak for themselves. If you’ve never used frozen puff pastry before, let me assure you that it couldn’t be easier.
