Wash the zucchini, cut off the ends and cut into “spaghetti” with a spiral cutter, including the peel.
Heat the oil in a pan and gently heat the zucchini spaghetti.
Meanwhile, blend the avocado flesh, washed basil and parsley leaves, walnuts, lemon juice, salt, and chili flakes in a blender until creamy.
Mix the mixture with the zucchini spaghetti, sprinkle with pepper and serve the zucchini spaghetti with avocado nut sugo.
