Heat oil in a pan.
Add chopped tomatoes to it.
Add turmeric powder & after 2-3 minutes add sliced capsicum.
As the mixture starts leaving oil, add salt, red chilli powder, garam masala powder & mix well.
As the mixture leaves oil, add water to it & mix well.
Allow water to dry up on a low flame.
As water dries up, capsicum will become soft & in case it does not become soft, roast the mixture for another 2 minutes.
As this is done, add tomato ketchup on a low flame.
Mix it well & then add paneer cubes into it.
After mixing it well, paneer capsicum is ready to serve.
