To prevent the Raita sauce from being soggy or watery, squeeze out as much moisture as possible from the grated cucumber.
When cooking the chicken, let it sit for about a minute to a minute and a half to build a crust before mixing it through. Repeat this to build color and prevent overcooking.
For assembling, place the Raita down first, then the Tandoori chicken, followed by red onion, coriander, and finally a lettuce leaf.
When wrapping, fold the sides in and then roll it over, tucking it in as best as possible. Store it on the seam.
For storing fully assembled wraps, place them in the fridge for up to 4 days.
If freezing, only freeze the cooked Tandoori chicken and allow it to thaw overnight before reheating or eating cold, to avoid soggy wraps.
