Slice each Party Potato Roll in half lengthwise.
Use a knife or kitchen shears to cut a hat shape from each pepperoni. Attach a pepperoni hat to each roll half using a dab of ricotta.
Using a piping bag or a plastic bag with a hole cut into one corner, pipe a ricotta beard and hat trim onto each Santa roll. Add two celery slices side by side atop the beard to make a mustache. Add three capers in between the hat and beard to make the eyes and nose.
