Preheat the oven to 200 F.
Next, cut the eggplant lengthways into 1/2 inch thick slices. Cover with salt, layer in a strainer and leave to drain for 40 minutes.
While the eggplant is draining, make the chermoula. Put all the ingredients with only 4 tablespoons of the olive oil into a food processor with a good pinch of salt. Blend to a thick paste and stir in enough of the remaining oil to make a sauce.
Pat the eggplants dry and in batches, brush with oil and in a griddle pan, grill over a medium heat for 5-6 minutes each side, until golden. Keep warm in the oven while you cook the remaining slices.
When all slices have been grilled, lay on a platter and dollop with chermoula, a sprinkling of coriander and pinch of sea salt.
