How many calories are in the average 10 inch sasauge pizza?

Question

cause my friends decided to order in from this restaurant and im on this excersice program in which i have to keep count of my calories

Answer 1

Somewhere around 300-800 calories for one slice, but it depends on the brand/size of the slice, plus the amount of sausage/cheese/sauce used.  I have listed some examples in the sources.

By the way, most places have nutrition information that you can find online, or you can request info. :)

Answer 2

somewhere between 10 and 900,000,000
