3/4 cup coarsely chopped green olives, preferably picholine
1/2 cup very finely diced red onion
Salt and freshly ground pepper
Endives, radishes, cucumbers and cauliflower florets, for serving
Skin the trout and break the fish into large flakes. Transfer the trout to a bowl and add the remaining lemon-caper mayonnaise, chopped olives and red onion; season with salt and pepper. Stir the spread until the fish is broken up but still slightly chunky. Serve with endives, radishes, cucumbers and cauliflower florets.
