White beans and tuna salad

Cut the onion, tomato and olives into small slices and place them in a bowl. Add the tuna with the olive oil from the can as it will serve as a dressing for the salad.

Drain the beans with a colander and wash them a little under the tap. Add them to the bowl. Add salt and vinegar to taste. Mix all the ingredients. Finally add the hard-boiled egg cut into pieces, so that it does not break excessively when stirring.

You can keep it in the fridge to keep it cooler or to eat it another day. A great tupper!
