A pie of tuna, tomato and mustard, this is a version of pie salt that I make very often, and that I had not yet shared with you. In the winter, when I really want, it happens to me to do it anyway but I will be replacing the fresh tomatoes with crushed tomatoes. We often see pie tuna and tomato or tomato and mustard, but from my side, I love the balance of 3, between the strength of the tuna, the sweetness of the tomato and the spiciness of the mustard!

I made this little tart for me, all alone, in a mini-pie, but in the recipe I have adapted the quantities to make a cake of medium size, for 4 people. Accompanied by a good salad, this tart tuna, tomato and mustard is a treat.
