Ham, Gruyere and Apple Sandwich

1 loaf Panera Ciabatta bread
1/4 pound deli-sliced ham
2 ounces thinly sliced Gruyere cheese
1/2 apple (your favorite variety), thinly sliced
Dijon mustard
1 teaspoon butter (for hot sandwich only)

Served on Panera's Ciabatta Bread

For a cold sandwich, slice the Ciabatta lengthwise. Spread each half with Dijon mustard. Layer cheese on one half. Fold slices of ham on top of the cheese. Top with the apple slices. Cover with the other half of the bread. Cut sandwich in half to serve.
For a hot sandwich, slice the Ciabatta lengthwise. Spread each half with Dijon mustard. Sauté the apple slices in a teaspoon of butter in a non-stick pan just until tender. On one slice of bread, layer cheese, then apples and top with ham slices. Top with remaining bread. Heat the sandwich on a grill press or grill pan until warm and cheese has melted slightly. Cut the sandwich in half to serve.
