First of all heat 1 tsp oil in a non stick pan on a medium flame, when oil is hot add cut mushrooms and corn, season to taste with salt and pepper.
Saute it till mushrooms get cooked, mixture should become completely dry so cook till all water evaporates, don’t keep wet either roll will be soggy.
Switch off the flame and let it cool down, now put ¾ tbsp hung curd or mayo and tomato sauce, mix well and spreader is ready.
Now to assemble the wrap, keep 1 phulka or roti in a dish, apply spreader, spread it evenly all over the phulka.
Now add 2 tbsp of mushroom and corn mixture in the central part, on that put on the top cabbage, carrot and lettuce leaf, put some shredded cheese on veggies.
Now sprinkle some salt, chilli flakes and pepper on it then fold from both sides and the wrap is ready to serve.
