Tuna Mayo Tortilla Sandwich
In a large mixing bowl, combine the tuna, mayonnaise, yoghurt and lemon juice with some seasoning until smooth.
Lay the tortillas on a flat surface and distribute the tuna evenly on them, spreading it to the edges using a knife.
Arrange some of the lettuce leaves on top and fold one end inwards towards the centre of the wrap. Roll the tortillas up like a cigar to form a wrap.
Cut in half diagonally and arrange the halves balanced on one another before serving.
