Heat oil in a pan and add the cumin seeds. Once it splutters a little, add the chopped onion.
After the onion turns translucent/golden brown, add the grated ginger and sauté a bit.
Next, put the chopped tomato on to the pan and salt as per taste. Sauté until it turns soft.
Add turmeric and the chili powder. Mix them all well and sauté for a couple of minutes. Check the salt and spice as per your taste.
Turn off the stove and add the crumbled paneer and coriander leaves. Mix well. Shift contents to a bowl.
Notes
You could use a toaster if you have, to prepare grilled sandwiches. For grilling on Tawa, apply ghee or butter on one side of a bread slice and toast it until it turns golden brown. Then, place a layer of the prepared paneer onto the slice. Garnish it with some grated carrots and beets and place another slice of bread over it. Press the second slice with a flat spoon/ladle.Flip the sandwich using 2 spoons and remove it from the Tawa after a minute or so. Serve it hot. You could have it as it is or with a flavor of tomato sauce.
