One of my favorite cocktails combines champagne with pink peppercorn and a few delicious herbal ingredients. With these bright, fresh flavors in mind, I created a marinated feta that is perfect for snacking, topping salads, or accompanying a charcuterie board.  The reddish pink berries and sprigs of bright green oregano – reminiscent of holly and winterberry – also make this a great appetizer for Christmas parties and winter celebrations.
