b'TO SERVE:For each entre-size serving, place the tuna mixture into a 3-inch cookie-cutter ring about 2 inches deep, pushing firmly to give the mixture a compact consistency. Carefully lift the ring off; the tuna will stay in the shape of a small cylinder in the center of the plate. Serve with slices of grilled toast. Make extra toast; your guests will ask for more!optional: For a more elegant look, decorate the perimeter of the plate with a drizzle of olive oil and balsamic vinegar.'
