I too, like Pam will eat it any of the above ways. I do like it cold, however rarely eat it that way. I usually first warm it slightly in the microwave then put it in the toaster oven to crisp it. I voted for the oven, because that is my favorite way to eat left over pizza. It's only my husband and I so we always have left overs.

Now I want pizza for supper, maybe tomorrow. Tonight is chicken.
