For stuffed capsicum:
Remove the tops of capsicums and remove the seeds and white edges inside.Grease the inner and outer side of capsicums with oil and arrange it on a aluminium foil lined baking dish.
Pour a tsp of tomato gravy(gravy 2) in all the capsicum shell and stuff 1 tbsp of potato stuffing and then pour again a tsp of tomato gravy and continue the process until the capsicum is completely filled.Take care that the top layer should be potato stuffing mixture.The addition of gravy in between the stuffed potato mixture makes the capsicums more juicy and tasty when you bite in and also will not make the capsicum dry.Repeat the process for all the capsicums.
Brush the top portion with some butter and keep the baking tray in the preheated oven @ 180 degrees for 15-20 mins until the edges of capsicum start slightly brown in color.
