In non-stick skillet, cook the onion in the oil. Add the garlic,
sundried tomatoes, black olives, and oregano. Remove from the heat. Add the goat cheese
and Parmesan. Season with salt and pepper and stir to combine. Stuff the chicken breasts.
Close delicately. In a baking dish, pour 250 ml (1 cup) of the sauce. Top with the chicken.
Cover with aluminum foil. Bake for about 20 minutes. Remove the foil and continue cooking for another 20 minutes or until the chicken is cooked through. Serve the chicken with the remaining sauce.
