heat 1 tbsp oil in a non stick pan/tawa or a well seasoned griddle. coat the paneer and veggies with the marinade and place them on the tawa. you can fry them at a low flame or medium flame.
in all i fried in 3 batches and overall used about 3 tbsp oil. another way is to skewer the paneer, veggies and then fry them. i chose to fry them directly as they get fried evenly and the texture is better.
when one side gets browned, gently lift and turn over. the paneer cubes will get cooked faster than the veggies.
you can can char or brown the veggies more. but remember to remove the paneer cubes as soon as they are golden. if you want you can fry the paneer cubes first and then the vegetables. remove them on a plate.
while still hot, then skewer the fried paneer cubes and veggies on to a wooden skewer or toothpick.
you can also have paneer tikka straight away without skewering. sprinkle some chaat masala & lemon juice on the paneer tikka.
arrange them in a serving plate and serve the paneer tikka hot or warm with pickled vinegar onions (sirke wale pyaaz), or pyaaz lachcha (onion lemon salad) or mint yogurt chutney.
