In a pan, add oil and butter, and once the butter is melted, pour oregano and chilli flakes and saute for a minute.
Then add the onions and ginger-garlic paste and saute for 1 minute on high flame. Moreover, add the bell peppers and again saute on high heat for 30 seconds.
Again add carrots and cabbage to the mix and saute on high flame for 2 minutes. Leave it aside for a few minutes for it to cool down.

Your filling for the kathi roll is ready and keep it aside for further use.
To make a soft, flexible dough, combine the refined flour in a bowl, add water gradually, and knead. The amount of water may be changed as needed.
To prevent the dough from drying out, generously oil it. Then, cover it with a damp cloth and let it rest for at least 30 minutes.
The dough should be divided into equal-sized balls and dusted with dry flour. To create a thick roti, cover it with dry flour, flatten it with your hands, and then use a rolling pin.
Set a griddle to medium heat, add a little oil, and cook the roti on both sides. Please avoid burning the roti and make sure the tawa is hot enough.
Take a freshly cooked roti, and put some of the fillings on either side. Add green chutney, ketchup, and roughly chopped onion on the filling if you like for extra flavour and crunch.
Roll the roti gently and your veg frankie is ready to serve.
