In a frying pan, heat oil. Add onions and sautee until golden brown. Remove to a plate. Add chicken livers to pan and fry until completely cooked, and no longer wet. Remove to a plate and let onions and livers cool completely.
Once cool, place livers and onions together in a food processor. Process, until desired texture, taking care not to over process, as chopped liver should have a bit of texture.
Place mixture in a bowl and add salt to taste, and a pinch of sugar. Add eggs and stir until blended.
