Mix the sausage meat with the nutmeg, herbs, sage, salt and pepper, then divide in 4 equal portions. With damp hands, form the sausage meat around the hard-boiled eggs in an even layer. Dip in beaten egg, then roll in matzo meal. Chill for 15 min so it firms up. Deep fry, two at a time, in 325F oil, 5-6 minutes until golden brown all over. Drain on absorbent paper. Slice in half width-wise and serve hot with grilled mushrooms and tomatoes, or cold with a salad.
