I am a big fan of both Pizza and Burgers' but I will only eat them out once a month.
I usually go for thin crust ham and pineapple Pizza, pineapple being a good digestive aid, or a Big Mack Meal in the case of a Burger.
The Pizza is more of a carbohydrate meal and the Burger is more of a protein meal.
If you are watching calories stick to the thin crust and limited topping on the Pizza.
On the Big Mack basicly throw away the Bun and the Fries because they are just sticks of fat, the Bun has no nutrition in it but the burgers' are good protien.
I make my own heathly Pizza and Burgers at home they taste better and are much better for you.
Hope this helps
