Mash the tuna with a fork and add the grated pickled cucumbers to it.
Add finely chopped onion, dill and mayonnaise. Mix it up.
On a baking sheet, pour vegetable oil and spread the pieces of the loaf with the finished spread. Thanks to the fact that the oil is poured in the end, we will get sandwiches on toasted croutons. It will be very tasty!
We lay out mugs of tomatoes and a piece of cheese. Put in the oven at 190C for 15 minutes.
