Go Hang a Salami! I’m a Lasagna Hog! and Other Palindromes (1991) by author and illustrator Jon Agee popularized a food palindrome (a sentence reading the same forwards and backwards). Agee described his thought process on his website in “20 Questions.”
 
Wikiquote credits the lasagna palindrome to Baby Gramps, but this is not correct.
 
 
Jon Agee—20 Questions
15. How do you write a palindrome?
One way is to look at the words around you - in your house, in a shop, in a park, or on the side of the road. Maybe you’re stuck in traffic, behind a SUBARU. You try spelling it backwards . . . URABUS. You add a D in the middle to get SUBARU DURABUS. Sure, it doesn’t make much sense. So you draw a picture:
 
You might be in the kitchen and pull out a box of frozen LASAGNA. Suddenly, you see that backwards, it spells ANGASAL, which for a palindromist, is very promising. So you fiddle with the backward spelling, separating it into possible words so you can build off it. ANGASAL . . . ANG A SAL . . . ANG A SALAMI . . . HANG A SALAMI!! Wow! Now you check to see what the backward spelling spells going forward: HANG A SALAMI the other way around is I’M A LASAGNA H!! You’re ecstatic! But you calm down, pull yourself together and eventually add the perfect letters to the front and back to complete the phrase: GO HANG A SALAMI! I’M A LASAGNA HOG! An excellent palindrome. But a picture always helps:

Agee insists that the best palindrome he’s conceived so far is “go hang a salami! I’m a lasagna hog,” which became the title of his first palindrome book. “Serious word aficionados had never seen the phrase. I must admit it is very classy,” Agee laughs.
