I guess frozen pizza (deluxe with all that greasy pepperoni and sausage) would be considered processed too.

Damn!
Now see I've made pizzas by hand but now were going too far.
I know pizza is prob the worst. All that white flour in the crust, all that grease, all that cheese.
Fact is I was a thin guy till I worked 6+ years at Dominos Pizza. I delivered four floor pies all night and still put on weight cause we could run out the door with a greasy slice on the hotbag almost anytime. Went from thin to a belly even though I worked an active job.
Nothing more fattening than Dominos. Check the charts.
True story.
