Meanwhile, cut the zucchini into pieces and sauté for a few minutes over fairly high heat with the other ingredients. Add oil if necessary.
1 zucchini, A generous splash avocado oil
Heat a little oil in the pot and transfer the zucchini to it once lightly browned on all sides.
Deglaze with the water and add the broth powder. Squeeze the lemon and add its juice. (If desired, squeeze it into a separate container first to catch the seeds.)
400 ml chicken broth (or chicken bone broth), 400 ml beef broth
Let everything simmer a little longer. Blend the soup once the zucchini is completely tender. Blend until smooth, or blend for a little less time to leave chunks in the soup if you prefer some texture.
Break up the walnuts by hand. Wipe the frying pan with paper towels and toast the walnut pieces in it.
1 handful walnuts
Reduce the heat under the soup. Grate the Pecorino and melt 50 grams of it into the soup.
100 g Pecorino
Divide the soup among bowls and garnish with the walnuts and remaining cheese.

Equipment: large PFAS-free frying pan, pot, grater (multi-sided), garlic press.
