6. If you have sliced the zucchini (courgette) yourself and prefer it softened, you can do this by adding the zucchini to the tomato sauce and stirring in. The heat will soften the zucchini. Alternatively, you can lightly steam or stir fry the zucchini strips until softened. You will preserve many more of the zucchini's nutrients if you eat it raw. A spiralizer is perfect for this as it will cut very fine slices. Or you can take an extra minute or so to slice your zucchini finely by hand.
