These clever tuna sushi sandwiches offer a fresh and fun twist on the classic midday meal. By rolling protein-rich tuna, crisp carrots, and refreshing cucumber into thinly pressed wholemeal bread, you create a handheld snack that is as nutritious as it is visually appealing. This recipe replaces traditional sushi rice with high-fibre bread, making it an accessible and speedy option for those who want the aesthetics of Japanese cuisine with the comfort of a British pantry staple.
Ideal for a high-protein lunch or a healthy after-school snack, these rolls are incredibly versatile. The capers and Dijon mustard add a sophisticated savoury depth to the tuna, while the crunch of the raw vegetables provides a satisfying texture. Pack them into a lunchbox with a side of fruit for a balanced meal that stays firm and delicious until lunchtime. They are a fantastic way to encourage children to eat more salad in a playful, bite-sized format.

Ingredients for Sushi Sandwiches
3 pieces of whole wheat sandwich bread
1 can of tuna (i use albacore in water)
1 teaspoon capers, chopped
1 tablespoon mayonnaise (plus more for spreading on the bread)
1/2 teaspoons dijon mustard
1 cucumber, cut into long, thin sticks
1 carrot, grated
How to make Sushi Sandwiches
Back to contentsCut the crusts off of each slice of bread and roll out as thin as possible with a rolling pin.
Place the tuna, capers, mayonnaise and dijon mustard in a bowl and stir to combine.
Place the long side of the rolled out bread closest to you.
Spread a thin layer of mayonnaise on each slice of rolled out bread.
Thinly spread 1/3 of the tuna mixture onto half of the bread lengthwise.
On top of the tuna mixture, arrange some of the cucumber sticks and grated carrot making sure not too over stuff the roll (a little goes a long way).
Starting at the side closest to you (the filled end) tightly roll the tuna/cucumber/carrot mixture up and press to seal into a roll (I dab a bit of mayonnaise across the end of the roll to act as a glue sealing the roll).
Cut the roll into 4 even pieces and repeat with remaining bread and tuna mixture.
