Delicious and nutritious tuna-filled casseroles, ideal for keeping in your Lent recipe book. Show off this simple dish with French influences to your friends.
For the dough, mix the flour, salt, and 100 gr of butter, rubbing with your hands until you obtain a sandy dough.
Add the egg yolk and water and knead until obtaining a homogeneous dough, being careful not to overwork it.
Place the dough in a clean bag and refrigerate for half an hour.
While the dough is chilling, finely chop the onion and lightly fry it in a pan with the remaining butter, without letting it take on much color.
Remove the onion from the heat and place it in a bowl, add the previously drained tuna, season with a little salt, and mix well; set aside.
Grease and flour a muffin mold for 6 portions.
Remove the dough from the refrigerator and roll it out carefully to a thickness of approximately 3 millimeters.
To form the little casseroles, cut the dough into discs larger than the base of the muffin mold, that is, approximately 10 cm.
Place the dough discs in the molds, pressing the dough into the base to thin it out and cover the entire mold; it should be thin in the end.
Brush the casseroles with mustard using a small spoon, being careful not to break them.
Add the tuna filling almost to the edge.
Cut the tomatoes into thick slices and place them on top of the tuna; if they are small, you can add several, and if they are large, one slice will suffice.
Add a tablespoon of cream, or enough to completely cover the tomato.
Season with salt and pepper to taste.
Bake for 30 minutes at 180°C, or until the dough is golden.
