Preheat oven to 300 °F/150 °C. Roast the walnuts until golden 10-15 min.
Use a food processor or high speed blender to blend chili, dried tomatoes, olive oil, a pinch of salt and garlic until smooth. Add the roasted walnuts and pulse until you have a chunky pesto and season to taste.
Use a julienne peeler to make zucchini spaghetti. Finely chop the soft core of the zucchini and mix it with the rest of the spaghetti. Cover the spaghetti with boiling water for 2-3 min and drain. Mix the spaghetti with the lemon zest and juice.
Stir in all of the walnut and chilli pesto. Gently mix it with fresh figs and crispy serrano. If you are very hungry serve it with some slices of avocado and a soft boiled egg. Enjoy.
