Most Italians spend a lot longer on eating dinner than they do with their lightning quick breakfast, hence the long menu. A primo piatti is the first course, usually smaller than a main but bigger than an appetiser. The secondo is the main dish and usually comes without vegetables which have to be ordered as a separate 'contorni'. Unless you are really hungry and go for all courses you can mix and match a starter with a primo or secondo, or just have the main and then head straight for dessert.
