Pumpkin spaghetti with sage pesto

Wash and lightly salt the pumpkin spaghetti; add a few drops of lemon, mix and let it rest. In the meantime, blend in the mixer all the ingredients, oil to taste and a little water every now and then, until you get a soft and creamy pesto. Season the spaghetti with a little pesto and sauté them in the pan for a few minutes with a drop of water. When the heat is off, add the remaining pesto and serve the dish.
