Don't expect anything more than what is visible in the food packaging.
The little plastic window in the packaging shows lots of pepperoni?
Don't assume the whole pizza is uniformly covered in pepperoni.
You'll just make an ass out of yourself.

I've seen pix of sandwiches where the packaging looks like there's tons of filling only to reveal that all the fillings have been jammed to the front of the package window.
