Fish with Vegetables and Mayonnaise

To prepare a delicious dish of stuffed fish fillets, we start by preparing the basic ingredients. Begin by salting and peppering the fish fillets to taste, and set them aside to absorb the flavors. In a separate step, prepare the vegetables: grate the carrot and celery on a large grater, ensuring you achieve a consistent yet slightly moist texture. Finely chopping the onion and garlic is essential to create a flavorful base, and the diced bell pepper will add a touch of sweetness and color to the dish.

Heat a pan with half of the butter, allowing it to melt completely. Add the onion and garlic, sautéing them over medium heat until they soften and become translucent. Then, add the grated carrot and celery, continuing to sauté everything until the vegetables become tender. Once the mixture is ready, set it aside to cool.

In another pan, heat the remaining butter and add the sliced mushrooms. Sauté them until they become golden and the moisture has completely evaporated. At this point, combine the mushrooms with the cooled vegetable mixture, seasoning with salt, pepper, and adding finely chopped parsley to enhance the flavors. Allow the mixture to cool well.

Next, move on to filling the fish fillets. Place 1-2 tablespoons of filling on each fillet, adding a few leaves of fresh parsley for an extra touch of freshness. Carefully roll the fillets, sealing them with toothpicks to prevent the filling from spilling out during baking. Place the rolls in a buttered baking dish, ensuring they are well secured.

Spread the remaining filling over the top of the fish, then cover everything with a generous layer of mayonnaise, which will add delicious creaminess. To finish the dish, evenly sprinkle grated cheese on top, which will form a golden and crispy crust at the end.

Place the dish in the preheated oven at a suitable high temperature, and let it bake for about 20 minutes or until the fish is fully cooked and the cheese has melted and formed a beautifully golden crust. This dish is served hot, perfect for a special dinner or to impress guests. The rich flavors and delicate texture will make this dish a true culinary delight.
