Recipe Notes

How much zucchini do I really need?

Garden grown zucchini and store zucchini are two VERY DIFFERENT sizes. Most of the time I make this dish, I am using two zucchinis purchased at the grocery store. However during the summer when I have zucchini to spare, I can made this recipe twice using one home-grown zucchini. 

The store zucchinis can yield anywhere between 1 cup and 1½ cups. 

Additional info on measurements:

Oregano, salt, and pepper are to taste. Depending on how fresh my dried oregano is, a little can go a long way. 

One large celery rib will be enough, so if yours yields a little more or a little less than my recipe indicates, you'll be just fine.
