Soft crustless bread triangles filled with tuna, capers, and mayonnaise are Italy's beloved tea sandwiches. This high protein mediterranean snack is ideal for clean eats and quick family lunches.
In a mixing bowl, flake the drained tuna thoroughly with a fork to break up any large chunks.
Add mayonnaise, chopped capers, lemon juice, salt, and black pepper to the tuna, mixing well until the filling is creamy and uniform.
Lay out the slices of white sandwich bread and gently flatten each with a rolling pin for a tender texture.
Spread an even layer of the tuna mixture onto half of the bread slices, covering to the edges for consistent taste in every bite.
Top with the remaining bread slices, pressing lightly, then trim away crusts and cut each sandwich diagonally into neat triangles; serve immediately or cover with a damp towel to keep fresh.
