Dannon (or as it's called in Spain, "Danone") has a Greek Yogurt product of different varieties sold in Spain, including Carrefour. Not sure about El Corte Inglés, however, but I'd bet they do. Don't think they'll have your specific, desired flavor, however. None of them seem to have granola. Might be a variety only sold in the UK (and/or other markets) Check out those sold in Spain at http://www.danone.es/Producto/griego/ .
