After trying this gremolata made from toasted almonds, onions, green peppers, and stewed tomatoes, you'll never think of eating a light, white fish another way again.
In a food processor or an electric blender, coarsely grind the almonds. Heat 1 tablespoon of the oil in a saucepan and stir in the almonds. Cook, stirring frequently, over medium heat, until the almonds are golden. Remove from the pan. Stir in the remaining 3 tablespoons of the oil, then add the onions and green peppers into pan; cook until soft, about 3 minutes. Stir in the stewed tomatoes, parsley, marjoram, sherry, and ground almond mixture. Heat through and keep warm. Season the fish with salt and pepper. Melt the butter in a frying pan and sauté the fish until golden and until the fish flakes with a fork. Transfer the fish to a platter and top with the almond vegetable gremolata. Accompany with stir-fried, cubed zucchini and hot cooked rice, if you wish.
