For the best results, preheat the panini press, and remember that it is better to cook a sandwich on lower heat for a longer time (rather than on high heat) so that the bread turns crisp and toasty without burning. Slightly stale bread will usually hold up better in a press than very fresh bread.
- 1Preheat the press. Evenly spread 1/4 of the butter on each bread slice and sprinkle with salt. Place 2 bread slices butter side down on a work surface and arrange the half of the cheese on each slice. Place the remaining 2 bread slices down on the work surface and spread half of the tapenade on each slice. Arrange the roast turkey on top of the tapenade and close the sandwich.
- 2Place the sandwiches on the panini press and grill until the cheese is melted and the sandwich is heated though, about 5 minutes.
