I just picked op a Mama Cozzi's Rising Crust 4 Cheese pizza and also a 3 meat pizza. A review I read rated Mama Cozzi BETTER than DiGiorno. One reason according to the review is that Mama Cozzi's is made by Aldi's in Europe (Germany where Aldi's is located) and that Europeans are much fussier about their frozen pizza so that explains the quality.
Tomorrow I am picking up 3 DiGiorno Rising Crust pizzas and will perform a taste test comparison myself on Sunday.
Truly, we have never been disappointed with quality in any of Aldi’s house brands (but their produce - meh). I don’t do grains, so when I buy pizza for hubby I only eat the toppings and the pup gets the crusts :-). Hope you have a fun party.
