Peel and finely dice the onion and garlic. Clean, wash and slice the mushrooms. Heat the fat in a pan and sauté the diced onion and garlic.
Add the mushrooms and fry until golden brown. Add tomato puree and season with salt, pepper and paprika. Put gnocchi in boiling salt water and cook until they float on top. Wash the chives, dab dry and cut into fine rolls.
Drain the gnocchi. Wash and finely chop the parsley, sprinkle the gnocchi with it and arrange on plates with the sauce. Sprinkle with chives.
