We make this bread all the time, especially when we have guests. The dough is the one I use for my everyday breads, sometimes adding yogurt if I have leftover that is going too sour or any kind of mashed vegetables or greens. In the summer I use a tomato-onion-olive oil mixture, the leftovers from our daily tomato salad, pulsed in the blender, to make my Tomato Salad Bread which can also be topped with cheese and tomato slices. 
See also the Smoked Cheese and Kumquat Bread which is basically the winter version of my topped breads. For a more spicy-aromatic topping spread Zaatar mixed with olive oil over the tomatoes.
Yields 2 laganes (focaccia-like flat breads), each serving 6-8 people as appetizer
