Wash the meat and slice it into pieces, rub with mustard, salt, ground black pepper, and oil. Fry each piece quickly.

Remove the meat and in the same pan, grate a large onion, fry and add 2 finely chopped garlic cloves.

Return the meat and add mushrooms, I used frozen mushrooms, sprinkle with ground paprika, thyme, and pour in water. Simmer covered until tender.

Make a semi-dark roux from plain flour, add more ground paprika, mix in a little water, and pour over the meat. Bring to a boil and it's done.

Peel and chop the potatoes, cook until soft in salted water. Drain and mash by hand, add butter, pour in hot milk, and mix with a whisk.
