Ingredients:
2 (5 ounce) cans tuna, drained
¼ cup mayonnaise
¼ cup finely chopped celery
1 ½ tablespoons finely chopped onion
1 tablespoon chopped parsley
¾ teaspoon red wine vinegar
1 pinch salt
1 pinch freshly ground black pepper
4 slices seedless rye bread
8 slices ripe tomato
8 slices Swiss cheese
paprika, for garnish
Directions:
Preheat the oven broiler.
In a bowl, mix the tuna, mayonnaise, celery, onion, parsley, and vinegar. Season with salt and pepper.
Place the rye bread slices on a baking sheet, and broil 1 minute in the preheated oven, until lightly toasted. Remove from heat, and spread with the tuna salad. Place 1 cheese slice over the tuna salad on each piece of bread, layer with a tomato slice, and top with remaining cheese slices.
Return layered bread to the preheated oven, and broil 3 to 5 minutes, until cheese is melted.
