Put all the ingredients except the olive oil and lemon wedges into a mortar and grind them together. Mix in the olive oil and rub whatever meat you are going to cook on both sides with this mixture.
Let the meat sit in the marinade for an hour or two or overnight. Barbecue in the normal way, but without added fat or oil, turning with tongs over a moderate heat, it is important not to overcook the meat, it must be juicy.
Serve with a slice of lemon, a green salad, perhaps potatoes and some good bread to mop up the juices. (Enough for 2 servings.)
