I could definitely eat chili and/or tuna repeatedly.
It's been so long since I've had canned ravioli, but I did used to eat it not and then. That, and the original Beefaroni, are the only 2 canned pastas that I would eat.
My sister would eat canned spaghetti or Spaghetti-O's, but that was not for me.
Spam was not something that I ate growing up, but they are advertising it fried these days, which is how I'd want it.
Interesting answers! :-)
