I too have suffered from the glut of Zucchini from my gardens. I lamented the lack of a good use for Zucchini (other than paper weights for my neighbors front steps).
At last, a recipe which actually TASTES like something you would want to eat...
Faux Dehydrated Pineapple
Full recipe:

You can also use Honey instead of sugar.
