I tried a whole bunch from the grocery store, and focused on finding one with the best crust. I then:

* only buy 3 or 4 meat pizzas

* add some cayene and mustard seasoning

* add my own fresh veggies

This fixes the bland, and meat seems to freeze well, veggies not so much.

And it takes 5 or 10 for the oven to warm, so cutting up some onion, maybe a green pepper passes the time.

Anyhow, I find this method very palatable.

As a side note, any kind of meat, especily pork, is really improved with mustard powder when cooking.
