Beat the eggs until light and foamy. Add the sugar, oil, zucchini, and vanilla and mix until well combined. Combine the flour, salt, soda, baking powder, and cinnamon and add to the egg-zucchini mixture. Stir until well blended, add nuts and dates, and pour into two 9 x 5 x 3 inch greased loaf pans. Bake in a preheated oven at 350°F for approximately 1 hour or until a skewer inserted into the center of the loaf comes out clean. Cool on a rack. This recipe can be frozen after baking.
