Detail not fotkal, all is very simple. Make the dough: dissolve the yeast in warm water with a pinch of sugar, pour in the oil, add a pinch of salt and flour to knead a soft elastic dough. The dough cover with plastic wrap and let rise. And in the meantime to prepare everything for the filling: onions cut into half rings (I had onions and a little green), cover with water and put it on a minute or two in the microwave to make it soft. Tomatoes pour boiling water for a minute, remove the skins and thinly slice. Sausage thinly slice. Grate cheese on a fine grater. While we do that, the dough has risen. It should roll out (if they do, it is possible to roll out dough to grease with vegetable oil), prick with a fork and place in oven at 180-200 degrees for 15 minutes. I have included a grill to the top flushed

Here such it turns out the cake. On it spread the filling to fluff mayonnaise, put onions, sausage, tomatoes and sprinkle with cheese

Bake using the grill or top heat to melt cheese and the emergence of a ruddy crust

Bon appetit!
