Omelet

Tortilla de ropa vieja was an unforgettably succulent specialty at Bar Astelena in San Sebastián. Alas, the bar has closed, but the recipe lives on. Thinly slice 2 medium-size yellow onions and cook them in olive oil over low heat until very soft but not browned. Transfer to a bowl and let cool, then toss with 2 cups of shredded beef, veal, and chicken from the cocido. In a separate bowl, beat 6 large eggs. Stir the eggs into the meat mixture, add some minced parsley, 2 tablespoons of cocido broth, and salt. Fry the tortilla as directed in the Potato Tortilla recipe.
