Preheat oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3). Wash the meat, dab dry, cut the rind with a sharp knife (also good: clean cutter knife) in a diamond shape.
Season the meat with pepper and a little salt. Place on the fat pan of the oven. Bake in the hot oven for about 2 1/2 hours.
Soup greens clean or peel, wash and roughly cut. Peel onions and dice 2 roughly. Spread the soup vegetables around the roast after about 20 minutes. After about 45 minutes gradually add 1/2-3/4 l water.
After approx. 2 hours, switch the temperature up (electric cooker: 225°C/circulating air: 200°C/gas: level 4) so that the rind becomes crispy. Mix honey and 1 tablespoon of water. Brush the crust with it about 10 minutes before the end of the roasting time.
Possibly switch on the oven grill in the last minutes, but observe the crust so that it does not burn.
In the meantime, finely dice 2 onions for the bean salad. Mix vinegar, mustard, salt, pepper and 1 pinch of sugar. Fold in the oil. Stir the onions into the vinaigrette.
Clean the mushrooms, wash if necessary and cut into fine slices. Cover the beans and cook in boiling salted water for 7-8 minutes until al dente. Drain the beans and put them back into the pot. Fold in mushrooms and vinaigrette and leave to stand.
Remove the roast and keep warm. Pour the roast stock through a sieve into a measuring cup. If necessary, fill up to approx. 600 ml with water. Bring to the boil in the pot, thicken slightly with sauce thickener and simmer for 1 minute.
Season with pepper, 1 pinch of sugar and a little salt. Cut the roast open, arrange everything. Roast potatoes taste good with it.
