Cut the meat into very thin strips.
Marinate for one hour in olive oil and paprika
Slice the mushrooms.
Cut the shallots in half lengthwise and separate the large petals.
Sauté the meat in a saucepan in very high heat, stirring so it doesn't stick, with salt and pepper in a little olive oil, draining the water as it comes out to avoid boiling.
Reserve in a saucepan.
Sauté the mushrooms in olive oil (truffled is best) and set aside.
Sauté the shallots with salt and pepper and add them to the meat.
Add a small bunch of dill.
Add the sauce without the cream. Mix well and cook for about ten minutes over low heat.
Add the cream, preheated to not interrupt the cooking, and cook over low heat until the cream thickens to a texture slightly thicker than double cream.
Add the mushrooms and cook for a few more minutes just to heat them.
Enjoy!
