1. Preheat oven to 400 degree F. Arrange the sliced bread on 2 cookie sheets and bake for 5 to 8 minutes or until lightly toasted, turning once.
2. Heat oil in a medium skillet over high heat. Add chicken livers. Sprinkle with sage, salt, and pepper. Cook, stirring, until livers are browned. Transfer to a medium bowl. Melt the butter in the skillet. Add onion and cook about 3 minutes or until tender. Return livers to skillet with brandy, then cook over high heat until brandy is evaporated. Remove from heat and mash with a spoon until blended. Spread 1 tablespoon liver mixture on each toast slice and sprinkle with parsley. Makes 24 appetizers.
