Provolone cheese has a firm texture, a mild, smoky flavour and golden-brown rind. It is an excellent cooking cheese, well suited to grating, melting and slicing.
Variation: Replace the tuna with 1 cup chopped chicken.
Combine tuna, parsley, cheese and mayonnaise in a bowl. Season with salt and pepper. Mix well.
Place 2 slices bread on a board. Lightly spread with butter. Top with tuna mixture. Spread remaining bread with butter. Sandwich together. Spray both sides bread with oil. Place in a sandwich press and cook for 4 to 5 minutes or until golden.
