In the bowl of a stand mixer or a large bowl with a and mixer, combine the first 4 ingredients.
Shape the mixture into a long log on a piece of plastic wrap.
Press the chopped parsley onto the cheese long on all sides, except the bottom.
Wrap the log semi-tightly with the plastic wrap and chill for 30 minutes.
After chilling, work the log (non-parsley side down) into a circle shape on a round serving platter, pressing and pinching as needed to make a wreath shape.
Garnish the inside of the wreath with additional cherries and pistachios (if desired) and press a red bow in the cheese.
Cover and refrigerate at least 30 minutes, or until ready to serve.
