You may want to also ditch the balsamic vinegarette and switch the f/f cream cheese to regular full fat cream cheese. I believe Atkins mentions something in the book about not having balsamic vinegar as it has extra carbs. As for the cream cheese, fat free types tend to have added carbs and other additives to give them their "flavor". The fat content shouldn't matter since most of your caloric intake should come from fat if you're following the Atkins plan (correct me if I'm wrong).

Good luck!
