What are traditional Swiss Christmas foods?

I live in Lithuania. That's not far from Switzerland. However, it would be hard to answer "How is Christmas celebrated in my native country?" I say thus, because the celebration of the Christmas isn't the traditions of gifts exchange or the alike things, but the act of the personal faith. Though the Christmas is the individual but they join all the faithful in one hug of omnipotent gratitude therefore.
they make a special cheese called "gustinti" and dance the "pyorta" at mass.
