Position a rack in the upper third of the oven. Preheat the oven to 450 degrees Fahrenheit. Lightly oil a 13x9-inch baking pan.
Combine the tomatoes, onion, celery, wine, parsley, oil, garlic and red pepper flakes in a medium bowl. Set aside while the oven is preheating.
One at a time, place a chicken breast half between two plastic storage bags. Using a flat meat pounder or a rolling pin, pound the chicken until it is 1/2-inch thick. Season with the salt and black pepper.
Arrange the chicken in the prepared baking pan. Spoon equal amounts of the tomato mixture over each chicken breast half, then pour any of the liquid in the bowl around the chicken. Bake until the tomato mixture is hot and the chicken is opaque throughout, which takes between 15 to 20 minutes.
Transfer each chicken breast half with its topping to a dinner plate, then pour the pan juices on top. Serve hot.
Making this for dinner tonight! I’m going to coat it in a little panko & also put some thin slices of lemon on it while it’s baking for some extra flavor! I saw Teresa making it on the Today Show (or something like that!) this morning so I thought I’d make it for dinner (: It’s something like 270 calories per serving, I believe!
