This is great as an appetizer or to take along on a picnic, the flavors really meld together well. The green olives really shine with the citrus flavor, so I use 2 cups green olives and 1 cup Kalamata olives. I double the garlic, orange peel and add 1 Tablespoon fresh thyme. The cooking time is the marinading time. This is adpated from Bon Appetit magazine, July 2000.
