How to Make It
In a deep skillet that’s large enough for the fish fillets to lie flat without overlapping, combine the tomatoes, olive oil, garlic, parsley, chile, a large pinch of salt and the water. Cover the skillet and bring the water to a steady simmer over moderate heat; simmer for 45 minutes.
Uncover the skillet and boil the liquid until it has reduced by half. Add the fish, skin side up, and cook for 2 minutes. Using two spatulas, gently turn the fillets. Season the fish with salt and simmer until just cooked through.
Put the grilled bread in shallow bowls and arrange the snapper fillets on top. Spoon the broth all around and serve.
