1

To make sushi sandwich (onigirazu), mix chicken and mayonnaise in a small bowl. Season with salt and pepper and set aside.

2

Cut a rectangle of plastic wrap (see tip), about double the size of your nori sheet and place on top of a chopping board. Place nori sheet on top, shiny side down and rotated 45°. Use a pastry brush to very lightly coat the nori sheet with water (do not over-water). Using wet hands, place half the rice in the middle of the nori sheet and shape into a compacted square. Top rice with avocado, spinach and chicken mixture. Gently press down to compress layers, then using wet hands, top with remaining rice.

3

To enclose sandwich, fold the right corner of the nori sheet over the top of filling, then fold over the left corner. Repeat with the top and bottom corners to create a square parcel. Wrap parcel tightly with plastic wrap, flip over and press down gently to compress sandwich. Set aside for 10 minutes.

Meanwhile, to make slaw, combine carrot, edamame and soy sauce in a small bowl. Season with salt and pepper. Transfer to a single compartment of your snack box.

5

Place egg in a separate, single compartment and sprinkle with chilli flakes (if using).

6

Remove plastic wrap from sushi sandwich. Using a very sharp knife, carefully slice sandwich in half and place into a double compartment of your snack box. Seal snack box with lid and place in the fridge until ready to eat.
