Sure. Make stock. Or shred them into a soup with wonderful mushrooms. Or off the top of my head, puree them with chicken livers, hearts, and giblets and other chicken offal; brown, drain, mix in some minced garlic and herbs, mould into croquettes, bread, fry. Serve with haricot vert or knotted and fried Chinese long beans and a sharp soup. Or smoke them. Great with chopped avocado, chipotle paste, and watercress in a sandwich. Otherwise they make great food fight items. Or just leave them. People buy more orf them than any other part of the chicken.
