Put all of the ingredients, except the sardines, into a bowl and mix together with some seasoning. Pour into a baking dish, add the sardines and toss really well. Cover and chill for a few hours.

Heat a BBQ or griddle pan until hot. Cook the sardines for 4-5 minutes on each side or until really caramelised and charred. Put onto a serving plate, drizzle with oil, sprinkle with a little more paprika and squeeze over the lemon wedges.
