Open Faced Tuna Melt:
Preheat the oven to broil, or use a toaster oven. Lightly butter one side of each bread slice and place them buttered-side down on a baking sheet.
Spread the tuna mixture evenly over the bread. Top with a slice of cheese. Broil for 3-5 minutes or until the cheese is bubbly and slightly golden.
Closed Tuna Melt:
Heat a skillet over medium heat. Butter one side of each bread slice. On one slice, buttered-side down, spread the tuna mixture.
Top with cheese and the second slice of bread, buttered-side up. Cook in the skillet for about 3-4 minutes on each side, until golden brown and the cheese has melted.
