SinoChef and Bob,
I believe that the emphasis on "real" is to differentiate the Pep product from frozen pizzas that use a mozzarella cheese substitute and soy-based products as substitutes for meat, in whole or in part.
I took a look at the ingredients used to make a frozen Totino's pepperoni Party Pizza. The Mozzarella Cheese Substitute comprises the following ingredients: water, palm oil, rennet casein, soybean oil, potato starch, vital wheat gluten, sodium aluminum phosphate, salt, potassium chloride, citric acid, potassium sorbate [preservative], sodium citrate, sodium phosphate, titanium dioxide [artificial color], maltodextrine, magnesium oxide, zinc oxide, riboflavin, Vitamin A palmitate, Vitamin B
12. The Pepperoni Pizza Topping for the pizza lists soy protein isolate as one of its ingredients (as well as mechanically separated pork chicken and beef).
Now, if you prefer a Totino's sausage pizza, the Cooked Pizza Topping includes both textured vegetable protein (a soy-based product) and soy protein concentrate. The topping contains some real meat products (mechanically separated chicken and pork) but it is not all meat.
Please stop picking on Pep

. His emphasis on using real cheese and meats, assuming that that is actually true, makes good marketing sense, even if it does not take much brainpower to state it.
