Sure, you can add zucchini to your spaghetti recipes, but you can also use it in place of noodles altogether. So called zoodles are a great pasta alternative, and they re easy to make with the help of some kitchen gadgets. With a mandolin or a spiral slicer, you secure the zucchini on prongs and push the veggie toward the blades. A smaller and less expensive option is a julienne peeler, which has a serrated blade to create thin strips.
