Porri in umido is a traditional dish originating from the southern parts of the country. It's made with a combination of leeks, black olives, olive oil, garlic, tomatoes, salt, pepper, and lemon juice. The leeks are chopped, blanched, and drained, then added to the pan with sautéed garlic, tomatoes, and olives.

The dish is seasoned with salt and pepper, and it's then simmered over low heat. Before serving, the lemon juice is stirred in for an extra kick of freshness. Braised leeks with tomatoes and olives can be served as a standalone dish or as an accompaniment to meat dishes.
