* Pearl onions and garlic cloves should be parboiled and peeled. ~------------------------------------------------------------------------Preheat oven to 180ºC . In a heavy pot that can be covered, combine all the ingredients except the feta, walnuts and half cup parsley. Cover tightly and bake for 1.5 hours or more, until the meat is very tender. Lower the oven temperature during this time, so that the contents of the pot remain at a gentle simmer. Skim off the fat. Do not boil the sacue down; it should remain rather thin. Ladle the stew into a deep platter. Granish with feta, walnuts, and the remaining parsley.
