Ask don't seem to have a calorie list on line for their meals. But if you look at this calorie information site you can get a pretty accurate idea. Penne itself is about 350 calories, and on the right hand site of the site there is a database where you can search 50000 foods, so you can look up chicken, sauce etc. Always remember though, that home cooked food mainly has fewer calories than what you buy ready made or eat in a restaurant.
