I voted for Digorno, but Mama Rosa's, I think it is, makes these little 4 packs of refrigerated/frozen (depending on the store) mini-pizzas that I love. They're great in a toaster oven, microwave is obviously trashier but a guilty pleasure for me, for soggy quick pizza. Reminds me of pool snack bars, I think that's what they served, at least around here.
Digornos deep dish is pretty tasty too. And the stuffed crust too. Straight up pepperoni. Nothin else.
