For dough: Mix flour, salt and yeast. Add oil, water, and mix. Knead 5-10min on floured surface. Raise in oiled bowl until double, 1-2 hours.
For topping: Saute onions in oil until golden (10 minutes or so), adding garlic after 5min. Shred kale, add to onions and cook til bright and wilted slightly, 5 minutes. Season with salt and pepper.
To assemble: Roll out dough into 3 bases (as thin as possible), and place on preheated (ideally), oiled (and polenta-sprinkled if you like) baking sheet. Spread each with a third of the kale, top with a third of olives, trickle with oil. Bake in preheated 220C oven for 10–12 minutes. You’ll never go back.
