Piselli con prosciutto is a traditional dish originating from Rome. It's made with a combination of sweet and tender Roman green peas, prosciutto crudo, butter, onions, parsley, salt, pepper, and chicken or beef bouillon. If desired, minced fresh mint can also be added to the dish as it's well known that peas and mint go together hand in hand.
The onions, prosciutto, and parsley are sautéed in butter, followed by the peas and the bouillon. The dish is seasoned with salt and pepper and cooked over low heat until the peas become tender. Before serving, it's recommended to sprinkle chopped mint on top of the dish.
