Shell the fava beans and the green peas (keep them separate). Peel, seed and chop the tomatoes. Slice the onions. Wash and slice the zucchini without peeling them.
Clean, rinse and mince the basil and parsley. Place all the vegetables in a pot in this order: first the tomatoes at the bottom of the pot, then the onions on top, the zucchini over them, then the lettuce and the green peas; finally, sprinkle with half the parsley and add the fava beans. Drizzle with oil.
Cover the pot and cook over medium flame. Do not stir for about 10 mins., until the vegetables at the bottom of the pot release their water.
Add the beef broth, a pinch of salt and a pinch of pepper. Stir, cover the pot and let cook on a very low flame for about an hour (do not add any water while the minestrone is cooking.) When ready, add the rest of the parsley and serve.
Note:
Neither rice nor pasta should be added to this minestrone.
