Tuna Canapés

COMBINE tuna, mayonnaise and media crema in medium bowl, stirring to break up tuna. Stir in sliced lettuce, tomato, onion, salt and pepper.

CUT crusts from bread slices; discard. Place 4 slices of bread in a large square shape, overlapping edges slightly. Press down lightly to seal overlapping edges. Spread 1/2 cup tuna filling over bread; roll up. Wrap in plastic wrap and refrigerate for at least 1 hour. Repeat with remaining bread and filling.

REMOVE from plastic wrap and cut into 1-inch-thick slices. Serve over lettuce leaves.
