For Crispy Panner :-
In a bowl add the diced Paneer and in that paneer add black pepper, and salt as per taste. Once it is mixed add Corn Flour in it and mix it well. Once it is all well combined remove the excess corn flour.

For Frying the paneer. Take a pan and add some oil into it for frying the paneer. You can also shallow fry the paneer, until its golden brown.

For Preparing Sauce you will need an iron wok or a pan. Add 2 tbsp oil, once the oil is heated properly add finely chopped garlic and once it turns out all aromatic and golden brown add some finely chopped green chillies. After that add chopped onions and sort it for a few seconds until its golden brown.

Now, add finely chopped capsicum and finely chopped red and yellow bell pepper (I didn't have that at the moment, so I have skipped it) yet you can add that too. Once it is all cooked properly add salt as per taste, crushed black pepper and dark soya sauce.

Then add some water into it and once it comes to a boil then add cornflour slurry into it. Once the sauce gets thick, slow the gas flame and add the fried paneer and toast for a few seconds. Lastly add some vinegar or a few drops of lemon, chopped coriander and spring onions.
