My style is a smash and grab for a wrap. I just fly through discounted salads that would make a great wrap and then hunt down fillers and sauces that appeal.
Favourite being a sprinkle of curry powder, mayonnaise, sun dried tomato strips, artichoke heart strips, shredded lettuce, and a salad mix all drizzled in lemon and sweet chilli sauce. For the kids I add some thinly sliced nuggets.
Hopefully a half decent wrap is on sale too.
