We will prepare all the ingredients. The flour should be sifted, the pineapple should be washed.
Knead a not tight dough, combining flour, salt, sugar, yeast, water and olive oil. Cover and put it on for an hour and a half.
Meanwhile, peel the pineapple and cut it into circles, removing the middle.
When the dough is suitable, you need to knead it. Cover the baking sheet or form with parchment and grease it well with oil.
Stretch the dough to the size of the mold, cover and let it come up again.
Put the pineapple in half rings on the dough that has come up for the second time, slightly pressing it. Spread the rosemary on top. Place in a preheated 200 degree oven for 15-20 minutes. The main thing is not to over-dry!!! (as I did...)
You can serve it both warm and cold. It's very tasty.
