Slice your zucchini into thin spaghetti-like strips.
Heat the oil on a big, stainless steel frying pan. Sauté the zucchini strips for around 5 minutes over high heat to make it a little crispy. Stir well with some salt and pepper.
Transfer the zucchini to a pasta bowl and generously pour in the pesto sauce. Garnish with some walnuts and Parmesan cheese on top. Enjoy!
