Wash the zucchini and cut off their tops. Dry them and cut into round slices about 1/4″ (0.5 cm) thick. Put the flour and salt in a bowl, pour in the chopped zucchini and stir very well.
Smear an oven dish with a little oil. Arrange the zucchini slices in it, overlapping them a bit. Sprinkle with breadcrumbs. Pour a very thin trickle of oil on top.
Bake about 40 min. at 392°F (200 °C) until reddened, take them out and leave to cool.
Serve them once cooled with a sauce of your choice. Yoghurt with garlic and dill, mixed with the oil from the baking is the classic option.
