I eat a lot of frozen pizza, because I love pizza. I never get DiGiorno unless I have to have one and it's the only choice. I prefer to buy ones that come from local parlors. They are most like a real delivery.
Even the best frozen pizzas I know that Whole Foods sells are only $7.99, so you are seriously exaggerating the price of DiGiorno.
I do order from the local parlors for fresh pizza once in a while, but they are very expensive.
I never buy from Domino's, Papa John's or Pizza Hut. They were never all that good, but the last few times I got them it was just terrible. Maybe you can get a large all the works pizza from them sometimes for $10,00, but I'd rather have frozen. Even Jack's, which go for about $2.00.
I tried Little Caesars once.
It is a good idea to buy frozen cheese pizzas and add your own toppings. Actually I get cheese and sausage because fresh sausage often doesn't cook right in the time it takes to cook the pie. I could brown the sausage ahead of time, but that's too much like work.
Then I add the best pepperoni I can find and fresh veggies, black olives and some more cheese. The veggies and olives I pick up a batch at a time from my store's salad bar. I have tried a lot of different pepperoni, but I haven't found a favorite.
I also use a pizza stone. The crust comes out usually perfect. I have a paddle and one of those batliff pizza knives too.
I need to go to the store!
