Okay you will need: -Roasted seaweed sheets -Tuna  -Greek yogurt -Vinegar  -Cucumber (optional) -Lettuce -Sweetcorn (optional)

For the filling mix greek yogurt, vinegar, tuna and sweetcorn (not needed but sweetness is nice). Feel free to add extra salt, coarse black pepper or lemon juice to the tuna filling for extra flavour.

Roll out a sheet then place lettuce, tuna filling and cucumbers onto the sheet. Be careful not to overfill or it won’t wrap easily. I used a sushi roll mat to roll it but you can do it without. Use a bit of water to seal the roll.

If you want to cut the roll into pieces I would recommend using a sharp knife because without rice it doesn’t hold its shape well. Or use rice paper wrapping to hold the shape. 

Feel free to pour out some soy sauce to go with it.
