Tips and Frequently Asked Questions

I used sharp cheddar in this recipe but any kind of cheddar or even other cheeses would work! If you prefer shredded Italian mix for example, go for it!
Don't skip the step to remove the extra liquid! You dish will become a little watery if you do. The grated zucchini will also have a better "bite" if you do it.
