The document describes a traditional dish from the Priorat region of Spain called "truita amb suc" or "omelette in juice". It is typically eaten on the second Sunday of March during Lent when meat is forbidden. A competition is held where local cooks prepare the omelette and the winners are chosen based on taste and appearance. The dish consists of an omelette made with eggs, spinach, and French beans served in a clay dish with a tomato-based juice made with onions, garlic, and spices.
