Beef and Arugula Bruschetta
Makes 16 (8 as first course, or more as part of buffet).
Note: For an elegant starter, make this with thinly sliced cold beef tenderloin and your own homemade giardiniera. For a super-quick version, use sliced rare roast beef and giardiniera (a medley of pickled vegetables), found in the pickle aisle of most grocery stores. From Lidia Bastianich.
