This is a classic frozen, ready-to-fry Spanish appetizer. A San Jacobo is a breaded and fried ham and cheese roll. It typically consists of a slice of ham and a slice of cheese (often a mild melting cheese like York or Emmental) rolled together, then coated in breadcrumbs. They are similar to a large, flat cordon bleu without the chicken. Designed for deep or shallow frying until golden and crispy.
