Cook shells according to package instructions; drain and cool. In a medium bowl, combine cheese, ham, turkey, croutons and tomato. Dressing may be added to this mixture or drizzled on after filling. Fill each shell with approximately 2 tablespoons lettuce and 3 tablespoons and meat mixture.

Serve immediately or store in covered container and refrigerate for up to 8 hours before serving.
