Add the sauce into a bowl and mix. Pour in the diced tuna and mix together.
Pour in the tuna into a ramekin and then place the diced avocado and cucumber into it. Use a fork to press the ingredients down into the ramekin.
Place a plate on top of the ramekin and flip it, the way you would a Spanish tortilla.
Enjoy alone or with wonton crackers or tortilla chips.
