Wash the plaice fillets, dab dry, cut in half lengthwise, sprinkle with 1 tablespoon lemon juice and chill. In the meantime wash parsley and chop it up to 4 leaves. Wash the tomatoes, peel them spirally with a peeler and turn them into a rose. Clean the mushrooms, cut fine strips from the centre of the mushroom head with a knife and sprinkle with the remaining lemon juice. Salt the plaice fillets, sprinkle them with parsley with the darker side of the skin facing upwards and roll them up.
Heat white wine in a pan, place the plaice rolls in the pan, cover them and let them simmer at low heat for about 8 minutes. Wash the salad and pluck into bite-sized pieces.
