Beat the eggs with the sugar and sunflower oil until the sugar is dissolved. Add salt, vanilla sugar + sifted flour with baking powder, spoon by spoon, then stir in the raisins + nuts + pineapple pieces + zucchini. If the batter is too firm, add a little more pineapple juice. Fill into a large greased pan + sprinkled with breadcrumbs. Bake for about 70 minutes at 175 °.
You can then put a frosting or powdered sugar on top (it tastes better with a topping because the cake is not too sweet).
