Grate zucchinis with a cheese grater using a small opening, place in large bowl.
Crack 3 eggs and combine with grated zucchini.
Stir in cake mix and combine thoroughly.
Add just a little water at a time if zucchini isn't moist enough to get to a thick, bread consistency.
Bake in a preheated oven at 350 degrees for 30 minutes.
Check bread, and if knife comes out clean, it is done.
If there is a little mix on the knife, cook for another 10 minutes, checking every five minutes, or until done.
