Then grind the tomatoes into a smooth puree

Now heat the butter into a pan & add the flour into it

Cook the flour until it starts to release a nutty aroma and then add the milk

As soon as you add the milk stir everything constantly in order to prevent any lump formation and continue stiring until the sauce is thick & it almost coats the flat surface of the spatula. White sauce is ready, keep it aside for later use

Now heat the oil in a pan & add the chopped garlic

Saute for few seconds & then add the onions

Fry the onions for a couple of minutes until they are transperent & then add the tomato puree

Cook everything for few minutes & then add the white sauce into the pan

Mix everything very well & at this stage you will start to notice that the sauce is turning into a peach pink colour

Then add the chat masala

Mix everything well & then add the cheese cubes

Cook until the cheese cubes melt & then add the pasta into the sauce

Garnish the pasta with some mint leaves & enjoy
