Agretti is an Italian vegetable - the name means "little sour." Other names for agretti are roscano or barba di frate. It contains the same vitamins and minerals as spinach, and can be prepared the same way as spinach; served raw in a salad, steamed, sautéed, cooked in omelets or soups.
Agretti is tolerant of salty soils and is sometimes compared to purslane.
