Réveillon pie needn't only be served after midnight mass-or even in the form of a pie. Here crunchy toast cups are filled ahead with traditional spicy pork and heated when needed. For more spicy heat, use Dijon mustard prepared with green peppercorns or horseradish.
These are wonderful served as an appetizer, especially during the Holidays, don't let the many steps scare you, this is actually very easy and can be made ahead.
