Add the tuna, yoghurt, mustard, sweetcorn, dill, olives, salt and pepper onto a chopping board and finely chop everything together until well combined.
Air fry the prosciutto at 180°C for 4–6 minutes until crispy.
Spoon the tuna mixture into the lettuce leaves, add sliced avocado, and top with crispy prosciutto.
Then fold and roll it just like you would a regular wrap — fold in the sides first, then roll from the bottom up to hold everything together.
Serve straight away and enjoy that perfect mix of creamy, crunchy and salty goodness.
