Firstly we need to make hung curd. If you are already having hung curd or thick curd, skip this process and proceed with 1 cup of hung curd.
To make hung curd, place a sieve over a bowl and add curd in it.
Place the bowl, with sieve carrying curd on it, in the refrigerator for 30 minutes.
In the meantime, cut the onion, capsicum and paneer into cubes.
After 30 minutes, take curd out of refrigerator and transfer it into a bowl.
Add , dry mango powder, chaat masala, black pepper powder, black salt, salt, lemon juice and mustard oil. Whisk well.
Put onion, capsicum and paneer cubes into curd mixture and mix gently so that everything gets coated well.
Cover the bowl and place it in refrigerator for 2 hours.
If you are using bamboo skewers, then soak them in water for at least 15 to 20 minutes.
Time to thread coated veggies on skewers. Take one piece of any veggie, let it be capsicum and thread on skewer. Likewise thread onion, paneer and in the same series repeat them as much as you want to thread on skewer.
Grease the baking tray with mustard oil lined with butterpaper or aluminium foil.
Place all skewers on tray and brush them with oil.
Oven was already kept for pre-heating @230℃ with only top rod on for 10 minutes.
Put the baking tray on top rack with only top rod on @230℃ for 15 to 20 minutes or until veggies are charred properly. If don't have oven, you can place the skewers on tawa and roast in the same manner from all sides.
Once they are done from one side, bring the tray out of oven, turn the sides of veggies (lower to top).
Brush the top again with oil and put back to oven for 5 to 10 minutes or until this side too gets charred properly.
Take the skewers out, squeeze lemon juice, sprinkle chaat masala and enjoy paneer tikka with green chutney.
