If you like, go ahead and use crumbled goat cheese instead of the blue cheese.
All the components of this recipe can be ready ahead of time. The pork can be cooked and in the refrigerator up to 24 hours in advance. The crostini slices can be baked up to 2 hours in advance. However, it's best to assemble the appetizers close to serving time.
Use your prettiest platter for these elegant appetizers! Arrange the topped crostini, then garnish with sprigs of fresh marjoram and fresh currants or cranberries.
