Preheat the grill to high. Skewer together and grill on both sides for a couple of minutes. This will take 2–3 minutes, turning over halfway through.
To make the dipping sauce, mix all of the ingredients together in a small bowl.
Serve with the dipping sauce in a small bowl. Spread the Mayo and siracha onto the baguette, remove the fish from the skewers and place inside the bread. Top with the nuts and the coriander.
