Combine the softened cream cheese and pineapple. Add the sugar and the pecans to this mixture. Trim the crust from the bread slices. Spread the cheese mixture on the bread slices and make into sandwiches. Place the sandwiches on a tray and cover with plastic wrap. Chill
When you are ready to serve, cut the sandwiches into thin slices about 1 inch in width and place on a decorative tray.
