In a large mixing basin, place the paneer and break it up with a fork.
Add the mashed potatoes, vegetables, milk, and all of the seasonings to it. Mix thoroughly.
Mix in the breadcrumbs and cornstarch to make a thick paste (the amount of breadcrumbs and cornstarch may vary depending on the consistency of your mixture). If it isn't sticking together nicely, add more of both.)
Divide the mixture into equal portions and roll and flatten them into patties.
On a griddle, heat 1 Tablespoon Vegetable Oil (per patty). Place the patties in the pan and leave them alone.
Allow for 4-8 minutes of frying on medium flame. It will be simple to shift the patty after the side has been done. Cook for another 4-8 minutes on the other side. Both sides should be crispy and golden brown.
In the meantime, toast some burger buns (optional)
Toss tomato slices and ketchup into the bottom half.
Place the patties on top of the bun. Add some slice of cheese (optional) and onions to finish it off.
Close the top half and serve hot with mint chutney!
