Zucchini is a long, slender, cucumber-like green vegetable that is also called squash. The green variant has firm flesh and a mild flavour. It can be lightly cooked and consumed with the peel as it contains beta-carotene and lutein. Chopped/sliced zucchinis sauted in olive oil and sesame seeds make a tasty side dish. Chop it into stews and spaghetti dishes or add it as a topping on pizza.
