Pinchos morunos would translate to Moorish skewers. They are a Spanish pork kebab (skewered meat) that's marinated with a spice blend called ras el hanout. The recipe originates in the Middle East and is likely a remnant of Spain's Moorish history (though they would have originally been prepared with lamb). They are currently very popular throughout Spain, especially in the south where they're common in Andalusia and Ceuta and Melilla.
