Beef or Veal Tongue in VinaigretteLengua en FiambreA classic way beef or veal tongue is prepared throughout Mexico is cooked, cooled, then eaten in a sandwich or served on a cold meat plate called fiambre. Usually tongue is served with marinated cooked vegetables. Other cold meats, such as sliced roast beef, are often added. I also like mustard and mayonnaise with tongue. Add whatever condiments you like.
