Put all the ingredients except the sardines and parsley in a blender and wiz until you have a rough paste.
Wash and dry the sardines and place them (skin down) carefully on a flat dish. Cover all over with the paste, and them cling film.
Marinade for a few hours.
Cook with the marinade in a preheated oven at 210 degrees Celsius, for 12 minutes.
Serve if you wish with more olive oil on top and sprinkle some fresh parsley.
