Absolutely, the paratha can be replaced with any flatbread whether that's homemade or store-bought, tortilla, thicker pancakes, or even with a pita bread pocket if you like. Yes, it will alter the taste but if you are in a hurry just go for whatever you like or have. An easier-to-make option will be to make crepes which means you will need to make a runny batter using the same ingredients listed above but add more water. You can also buy the ready-made wraps, these will be great for a work lunch or a picnic. For a super healthy option, a low-carb choice, you may even wrap the curried chicken in salad leaves (Chinese salad, gem lettuce, iceberg leaves) and serve.
