Place 2 lettuce leaves, overlapping with the stalk ends towards you
Take a quarter of the chicken, onion, carrot and peppers and place in a line along the bottom edge, the stalk ends of the lettuce leaves
Start to roll the bottom edge up, tucking in the sides as you go to hold the filling in
Repeat with the other 3 portions of lettuce leaves and filling
Cut each roll in half to serve
If making this in advance, sprinkle a little lemon juice over the lettuce to stop it discolouring in your lunch box
You can add mayo or dressing if you like, just drizzle a bit over the filling before rolling
Use any filling you like, maybe prawns in marie rose dressing, sliced crabsticks, avocado, red onion, apple, cheese whatever you like!
