This is another quick and economical recipe which tastes stunning, and authentically Mexican. You could also add fresh chilli if you wish, but the chipotle will make it quite hot. You could also add chopped fresh coriander, either at cooking time or to serve, but I think this is unnecessary.
I think the fajitas are lifted by copious quantities of lime juice so they have a real acid kick! This combines brilliantly with the smokiness of the paprika and chipotle.
