Put the flour in a bowl (I put about 200 gr). In the middle make a place where we put the yeast mixed with a little sugar and warm water. Leave until the yeast starts to rise. Then add a little salt and knead with warm water. Towards the end add a little oil and leave to rise.
When the dough has risen, spread a thin sheet, which we grease with a little tomato juice. Then sprinkle on top the mushrooms, ham, corn kernels, peppers, feta cheese. Then grate the cheese, add some slices of tomatoes and put it in the oven until the sheet is baked.
Yes daaaaaaa it was very good.
