Make a thick marinate of chili powder, ginger garlic paste and salt and marinate the prawns & keep aside.

In a chatti fry the prawns till half done & add the onions & green chilis

Once the onions change color add the tomato and cook till prawn are done

Garish with curry leaves & coconut oil

Tip : You can add water accordingly as per your gravy preference. I add tomato puree to make a thick gravy
