Cut the Paneer cubes. If you want to add veggies, dice them as well. Be sure to cut them in similar size as the paneer cubes.
In a medium mixing bowl, add all the ingredients under ' For marinade' and mix to get a smooth paste.
Add the paneer cubes (and the veggies) and marinate for a minimum of 2 hours (can be more as well) in a refrigerator.
After 2 hours, remove Paneer and let it come to room temperature.
Take a grilling pan and brush oil uniformly. Heat it.
Once heated, on a medium flame, grill the paneer cubes. The grill marks should appear on both the sides.
Remove and serve hot with a chutney and salad side.
