Fillet your mackerel and lay them out on a baking sheet lined with baking paper, cling film or foil.
Place the tray in the freezer for a minimum of 4 hours (please see safety warning in the article above).
Remove the fish from the freezer and allow it to defrost.
Prepare your vegetables as described above and toss them together on a platter.
Slice the fillets (as described in the step by step photos above) into bite-sized pieces of sashimi.
Layer the sashimi onto the salad. Scatter with the sesame seeds and rings of green onion.
Mix the soy sauce, toasted sesame oil and hot sauce in a small bowl.
Drizzle over the salad immediately before serving.
