Extremely simple appetizer for those who like sardines. From Gourmet, March 2002
Preheat oven to 375°F.
Trim crusts from bread and cut each slice into 8 triangles.
Mash sardines with mayonnaise, then stir in onion and parsley.
Spread on toasts and bake on a baking sheet in middle of oven until puffed and golden, 10 to 15 minutes.
