Paneer Kulcha might sound like a Paneer paratha with a stuffing of Paneer right inside the paratha while roasting but this is something different and pretty unique to Delhi style.
The stuffed Paneer Kulcha in Delhi is made with a ready-made plain Kulcha and then stuffing the Paneer Bhurji inside the two Kulcha layers to form a sandwich.
Interestingly, it is commonly known as Paneer Kulcha rather than a Sandwich.
Here is the recipe if you want to give it a try.
