Preheat the oven to 375 degrees.
In a large mixing bowl or a 9x13 baking dish, combine the vinegar, Dijon, olive oil, garlic, salt, and rosemary.
Add the chicken and kalamata olives and swish the meat around until coated in the marinade. Transfer the baking dish to the oven, or alternatively, marinate the chicken overnight, covered.
Pour the white wine into the pan and season the chicken lightly with salt. Bake in the oven for 45 miutes, until the chicken is very tender and the top is golden brown.
Serve alongside quinoa, rice, or some crusty bread.
