Any sturdy peasant-type bread will work in this dish, but we liked rosemary the best. Your bread should be slightly stale; if not, arrange bread cubes on a baking sheet and bake for 10 minutes at 350°.
Combine first 5 ingredients in a large bowl; cover and marinate in refrigerator 8 hours. Stir in vinegar.
Add bread and remaining ingredients just before serving; toss gently.
