Add the yeast to 2 cups of warm water (110 degrees F) with the sugar and honey. Set it aside for 5-10 minutes until the mixture gets frothy. In the meantime, shred the zucchini in a food processor or use a hand grater. Then add it to a blender to liquify it.
When the yeast is ready, mix the zucchini with the yeast mixture. Add all other ingredients except for the flour.
Add the flour and mix one cup at a time. If the mixture gets too stiff by mixing with a spoon, use your hands. You may need more than 5 cups of flour--add additional flour, enough so the ball holds together and makes a smooth, stiff ball.
Knead the dough for 5-10 minutes. on a lightly floured surface. I usually do it for about 7 minutes.
Put the dough in a bowl, cover with a towel, and set it in a warm place. I put it on my oven as it is pre-heating (set it at 350 degrees F). Allow it to rise for an hour, til doubled in size.
Punch the dough, knead it for a couple more minutes, and shape it into a ball.
For making artisan bread, make a few slashes on top of the bread. Scoring the dough with a bread lame or razor blade allows the dough to expand in the oven and let the gases release.
Place the bread on a baking sheet lined with parchment paper or a silicone baking sheet. Allow it to rise for another 20 minutes. While the dough is rising, preheat the oven to 425 degrees F.
Bake the bread for 30-35 minutes or until golden brown (top and bottom). Set it on a baking rack to cool when done. It is best to wait until the following day to eat--this allows the yeast to be completely finished working (it is also helpful for better digestion).
