Dissolve yeast in warm water. It is added to the flour in which you have previously put 1 tsp salt, pinch of sugar and 1 tbsp sunflower oil. Knead a soft dough. There is no need to do a lot of kneading and long enough to collect. Cover and leave to rise. Once it is ready to intervene again and spread out in a rectangular tray measuring about 20-35 cm of baking paper. Spread top with plenty of olive oil or sunflower oil and sprinkle with colored salt. I do it with salt, pepper, fenugreek, basil, but anyone can sprinkle it to your liking. Allow about 15 minutes to rise. Before baking can be dusted with a little olive oil. Bake in preheated oven at 200C 15-20 minutes. After removing the roof is to remain soft.
