Add diced tomatoes to the skillet, stirring well. Cook for about 10-12 minutes until the tomatoes break down into a sauce.
Gently place the seasoned fish fillets into the skillet, spooning the sauce over the top. Cover and simmer for 8-10 minutes until the fish is cooked through.
Remove from heat, squeeze lemon juice over the fish, and sprinkle with chopped herbs.
Transfer the fish to a serving platter and spoon more sauce over the top. Serve immediately.
