Make a pot of water with zucchini, a beef ball, 7 or 8 olives and a proper amount of zucchini fried beef balls. Cook the beef balls first, then wash and slice the zucchini. After the meatballs are cooked, cool and slice them, and pour a little oil into the hot pot. Stir-fry the zucchini in the pot, stir-fry the meatballs together, and add some olive vegetables randomly to taste. If the taste is heavy, you can add a proper amount of salt. If you like something light, you don't need to add it, because olives are salty.
