Marinate the paneer cubes, onions and capsicum in all the spices along with mustard oil. Set aside for 30 mins to an hour
Skew them on bamboo skewers, adding onion and capsicum every couple of paneer pieces.
In a heavy bottom fry pan, fry till it is brown on all sides. There is no need to add oil to the pan as our marinade has sufficient oil but if your tikka is sticking , add a bit of mustard oil.
