I can't for the life of me remember where this recipe came from but I have been making these for about 30 years now. Everyone absolutely loves them. I nearly always double or triple the recipe because we love them as snacks or in our lunch the next day. Go by the recipe and don't add any extra salt as there is enough in the cheese and crackers. Enjoy! P.S. 8-7-09 I have been making this for over 30 yrs. and have never had a problem with watery zucchini. Might just be a climate issue.
