To a bowl or pitcher, add the olive oil and balsamic, along with the garlic, parsley, basil, salt, and pepper. Whisk it until it’s emulsified. Place the chicken in a large zipper bag and pour in half the dressing. Seal the bag and set it aside. Halve the tomatoes lengthwise. Trim the ends off the green beans, and place the veggies in a large zipper bag. Pour in the rest of the dressing, then seal the bag and set them aside. Preheat the oven to 425 degrees. Arrange the chicken and veggies on a sheet pan, leaving the excess marinade behind. Roast in the oven for 25 minutes, shaking the pan once during that time. Serve with crumbled feta cheese all over the top and Pane Turano to soak up the juices.
