We mix in a bowl the yeast, the sugar and water. We leave the mixture in a warm place for 10 minutes.
We mix in a bowl the flour, the salt and the oregano. We add the yeast and mix, until our dough form into a ball.
We pour the olive oil into a baking dish, place the dough inside and we spread it out with our hands, until it almost covers the entire bottom of the dish.
We cover it with plastic wrap and leave it in a warm place until it doubles in size, approximately for one hour.
In two separate bowls, we mix the onions and tomatoes with a bit of olive oil and add salt and pepper.
Once the dough has risen, we first spread the onions and then put the tomatoes on top.
We cover it with aluminum foil and bake at 180 degrees Celsius for 40 minutes.
We remove the aluminum foil and continue baking for approximately another 20 minutes.
If we are passionate and want to make the “ladenia” even more delicious, we bake it in a wood-fired or a stone oven, adding cured meats and cheese we like, creating a modern version of focaccia.
