Cook the onions and apples in the butter, until tender, then season with curry powder. In a food processor, coarsely chop the nuts with the chicken. Add the cooked onions and apples and the egg and process just until combined and almost pureed. The mixture should come together but
not be pasty. Season with 1/2 teaspoon salt and freshly ground black pepper. Shape the mixture into 8 small patties. Dredge them lightly in flour and cook in butter for 3 minutes a side or until hot through.
Serve over a green salad or with cabbage. Delicious topped with sour cream.
