Change is bad, mmm'kay?

I've read articles recently about how family recipes are being ruined when companies change their sizes.  A lot of classic recipes skip measurements in favor of "One can tuna" or "small jar of diced tomatoes."  Now, this was find for years, when most things can in a standard size.  But with rising food prices, some companies are changing their packaging and not necessarily informing customers.

My dilemma is similar.  I grew up with a sloppy joe recipe that calls for a can of Campbell's Chicken Gumbo soup.  Problem?  They only make a light version now.  I'm going to try using the light version tonight but my hopes aren't high.  Usually when they make something light, they replace the good stuff with, well, crap.  Sadly it's this, or give up my childhood sloppy joes.  I hope this works!
