I tried a couple of Kashi chicken 'zas a while back, when there was a recall on Totino's pizzas with pepperoni and one of the supermarkets pulled all the Totino pizzas. I liked them, but I wanna caveat: the cooking instructions on the Kashi box say "heat oven to 425˚ and cook for [was it 15 minutes?]" while those for Totino's say "heat to 375˚ and cook for 10 minutes". My oven runs a bit hot (and we have a foil reflector on the bottom which makes it even hotter), and when I cooked the Kashis per the instructions on their box, the darn pizzas came out burned to a crisp
Using the same temperature for the Kashis as I do for the Totinos, and not keeping them in the oven so long, led to better and more edible results. So know your oven, and maybe cook them the same way you're used to cooking the 'za you eat now
