I McWish for 2 things:
Low carb buns
Bring back the salads or some healthy low carb alternative to Fries
Here in Australia I think they still offer a salad as a alternative to fries.
When we fix burgers (real meat) at home, I wrap mine in lettuce instead of using a bun. I can still include cheese, tomato, mayo and onion without the carbs. It tastes great!
