1oz. dried porcini mushrooms
1/4 lb. Swiss chard, stems removed
1/4 lb. spinach, stems removed
2 small zucchini, diced
2 medium white potatoes, peeled and diced
2 Japanese eggplants, peeled and diced
2 tbsp. extra-virgin olive oil
2 cups pasta
2 cups cooked white beans
2 tbsp. pesto (see recipe below) Freshly ground black pepper
Soak porcini in 2 cups warm water until soft, about 20 minutes. Remove porcini, rinse, chop and set aside. Pour porcini water through a coffee filter and reserve. Chop chard and spinach leaves.
Bring porcini water and 6 cups salted water to a boil in a large pot. Add porcini, chard, spinach, zucchini, potatoes, eggplant and oil. Reduce heat to low and simmer, uncovered, for 1 hour.
Add pasta to soup. Cook pasta for about 10 minutes, add beans and cook 5 minutes longer. Stir in pesto and season with salt and pepper. Serve hot or, in the Genovese tradition, at room temperature. Sprinkle with parmigiano-reggiano, if you like.
2 tightly packed cups stemless fresh basil leaves
2 tbsp. pine nuts
2 cloves garlic, peeled and chopped
1/2 cup mild extra-virgin olive oil
1/2 cup grated parmigiano-reggiano
Crush basil, pine nuts, garlic and a large pinch of salt into a fine paste with mortar and pestle. Drizzle in oil, stirring constantly, then stir in parmigiano-reggiano. Put plastic wrap directly on surface of pesto, then set aside. If using a food processor, put pine nuts, garlic and salt into the bowl of the food processor fitted with a metal blade and blend to a paste. Add basil, drizzle in oil and process until smooth. Transfer to a bowl and stir in parmigiano-reggiano.
