Preheat the oven to 180 ° C top / bottom heat (convection: 160 ° C).
Knead the mince, breadcrumbs, eggs, salt, pepper and paprika powder. Spread the chopping material as a rectangle (approx. 25 x 25 cm) on a slightly larger piece of aluminum foil.
Peel off the cabbage leaves, wash and pat dry. Cut the spring onion into rings. Top the minced meat with cabbage leaves, ham, cheese and onions. Roll up with the foil, place on a tray with the foil seam facing up and cook in the oven for about 30 minutes.
Then open the foil at the top, fold it open and finish cooking the roast in approx. 20 - 30 minutes. Remove the foil completely.
Mix the creme fraîche, mustard, salt, pepper and paprika powder. Take the roast out of the oven, cut into slices and serve with the sauce.
This goes well with potato salad, baguette or bread roll.
