In a saucepan heat olive oil over medium heat and cook onions until
tender. Add orzo and cook for 2 to 3 minutes. Add olives and 2 cups
of chicken stock and bring to a boil. Simmer for 5 minutes and 2 more
cups of chicken stock. Return to a boil and pour into a butter baking
dish.
Cover with foil and bake at 350°F for 20 minutes, stirring once.
After 20 minutes check orzo and if necessary add more stock and
continue to bake until tender. Sprinkle with fresh chopped herbs and
serve hot.
