Clean and wash the cabbage and remove the stalk. Cut the cabbage into wide strips. Peel and chop onion. Chop almonds and olives separately.
Wash the rosemary, dab dry and cut each branch into 3 pieces. Wash the meat, dab dry and possibly tap flatter. Season only with pepper. Cover with 1 slice of ham each. Spread 1 tablespoon of olives on each slice.
Roll up the meat. Insert 3 rosemary twigs crosswise at equal intervals, possibly pre-drilling with a skewer. Cut the roulades between the twigs to make 3 small rolls.
Heat 1 tablespoon of oil. Sauté onion and cabbage in it. Add 100 ml stock and braise covered for about 10 minutes. Season with salt and pepper.
Heat 2 tablespoons of oil in a large frying pan. Fry the rolls for 6-8 minutes. Remove and keep warm. Roast the almonds briefly in the frying fat. Deglaze with sherry and 300 ml stock, bring to the boil and simmer over high heat for about 5 minutes.
Season to taste with pepper and arrange everything. Roast potatoes taste good with it.
