LLENAR MEJICANO

Cut a pound of mild cheese into tiny bits. Prepare a cupful of olives stoned and chopped fine, one large onion chopped fine, and ten chile-prunes (that is, the dried shells of the chiles, without the seeds), toasted and crushed fine. To these add a pinch of marjoram crushed fine, a tablespoonful of olive-oil and a teaspoonful of cider-vinegar. Mix all well together, let stand an hour and then put between thin slices of bread and butter.
