Totinis frozen pizzas changed their description in last year or so. The new description says "pepperoni flavored pizza topping" now. Who defines what "pizza topping" is, however, IDK.
Flavored? It makes you wonder what those slices are actually made of.
Ah, now I googled and saw the box. It says "made with pork, chicken, beef". In no particular order and in variable proportions, I guess.
"mystery meat" doesn't have the same ring to it as "pepperoni flavored pizza topping"
