Zucchini e Pomodori Gratinati (Zucchini and Tomato Gratin)
If you wish to take a bit extra time, put the freshly sliced zucchini in a colander in layers, salting each layer as you go. Then place a suitably sized plate (or equivalent) on the top and weigh it down (scale weights are good for this -- although I have used big liter bottles of water before now and/or bags of sugar!). After 30 or so minutes, a surprising amount of water will have been drawn out. You can then dry the slices thoroughly with a clean cloth, or paper kitchen towel (careful not to leave paper behind!) and then they're ready for cooking.
