What is zucchini?
Zucchini is a summer squash. It is native to central America and Mexico but it is grown throughout the United States during the warm summer months. While you may think of zucchini as a vegetable it is actually a fruit. Zucchini and yellow squash are low in calories with a low glycemic index. Both squashes are a good source of vitamins A and C, fiber and potassium and they make a great zucchini gratin.
