In a large pan, heat the vegetable oil over medium heat. Add the 500 grams of prawns and let them fry for a few minutes.

Add the finely chopped onions to the pan and sauté until they become translucent.

Add the chopped tomatoes, turmeric powder, red chili powder, and salt. Cook the mixture until the tomatoes become soft and the oil starts to separate.

Pour in the coconut milk and let the curry simmer for a few minutes, allowing the flavors to blend together.

Adjust the seasoning if needed.

Serve the Fried Prawn Spicy Curry with steamed rice or naan bread.
