Cut 6 slices (each about 1 cm thick) from the rutabaga, peel and wash (use the remaining rutabaga for other purposes). Halve the turnip slices and cook in boiling salted water for about 12 minutes, remove and let cool.
Clean and clean the mushrooms and cut them into thin slices. Put 1/2 slice of ham and 1/2 slice of cheese on 6 half turnip slices and place the remaining turnips on top. Beat the eggs in a deep plate.
Put flour and breadcrumbs separately on plates. Turn turnip cordon bleu first in flour, then in egg and breadcrumbs. Heat oil in a large frying pan. Fry Cordon Bleu in it for 6-8 minutes at medium heat.
Heat the fat in a saucepan. Sauté the mushrooms for about 4 minutes. Add 250 ml water, bring to the boil and stir in the sauce powder. Arrange turnip cordon bleu on plates with the mushroom sauce. Garnish with parsley.
It goes well with rice.
