In a medium saucepan, heat milk to scald. Reduce heat and slowly stir in farina, cook until thick, approximately five minutes.
Remove pan from heat, stir in eggs, margarine, salt, pepper and beat until smooth. Spread mixture into a greased 13 x 9-inch pan, let cool. Cover pan and refrigerate for 2 to 3 hours until firm.
*Note* Refrigeration time for gnocchi to firm is included in the preparation time.
When firm, remove from refrigerator and cut gnocchi into 1 1/2 inch squares or circles. Place them overlapping, into an ungreased baking dish. Dot tops with 1/4 cup margarine and sprinkle with cheese. Bake at 350 degrees for 30 minutes or until brown. If needed you can brown a little more under the broiler.
