Carefully beat the meat under foil into roulades, taking care not to damage the meat fibers. Season with salt and pepper. Cover the roulades with the squeezed spinach and the ham, roll them up and tie them together.
Heat the butter and oil in a saucepan and quickly fry the meat on both sides. Deglaze with the wine. Add 250 ml of vegetable stock. Now put in the oven at approx. 150 degrees for approx. 35–40 minutes.
Remove the meat and pour the cream into the sauce. Season the sauce with salt and pepper and thicken with a little mixed cornstarch. Put the meat back in the sauce.
