In a large skillet, heat the vegetable oil over medium heat. Add the chopped onion and garlic, and sauté until fragrant.
Add the curry powder to the skillet and stir for one minute to toast the spices.
Pour in the coconut milk and chicken broth, stirring to combine.
Add the sliced bell pepper and let the sauce simmer for a few minutes to let the flavors meld together.
Gently add the fish pieces to the skillet, making sure they are covered in the curry sauce. Season with salt and pepper.
Cover the skillet and let the fish cook for about 8-10 minutes, or until the fish is cooked through and flakes easily with a fork.
Serve the curry fish over cooked rice or with naan bread. Garnish with fresh cilantro.
Enjoy!
