Frozen pizza is, well, frozen pizza. If you buy Red Baron, Tony's or Freschetta's, you're buying pizza made by Schwan's. If you buy DiGiorno, Tombstone, California Pizza Kitchen, or Jack’s, you're buying a Kraft foods pizza. I don't know who makes Wal-Mart pizzas, but to my taste, they're no worse (or better) than any of the aforementioned brands (but they are less expensive).
Today, everything changed. I visited a accountant (CPA) for the first (and I hope last) time - she was a former student of mine. When we were done, on the way home, I stopped off at Elvio's Pizzeria and Restaurant up in Lincoln. It was the best I have had in a long time! The taste and texture of the pizza today almost brought a tear to my eye (don't tell anyone, but I had four slices thinking I could store up the experience [I think I will be storing it around my waist area]). I guess there is hope. I still have plans to try a place called Sal's, which I am told is also good. I rarely travel for food, but maybe Lincoln really isn't that far.
