Method
Cut the fat off a sirloin steak and cut into thin slices.
Heat a little extra virgin olive oil in a health grill, and cook the steak strips, seasoning with salt, pepper and garlic. Transfer to a hot plate to finish off later.
Sauté the mushrooms, onion and garlic in a little butter in a pan.
Pour crème fraîche into the sautéed vegetables and leave to thicken for a minute. Add lemon juice and paprika to taste.
Return the steak to the pan and heat very gently for one minute ? the beef should not be cooked any further.
For the champ, cut and wash the potatoes and slice into quarters. Steam the potatoes in a health steamer. Add semi–skimmed milk, butter and fresh chives to the boiled potatoes and mash well.
Serve on a warm plate with assorted vegetables and garnish with parsley and diced chives.
