Chicken Soup For My Bowl

Is chicken soup a metaphor
In 'Chicken Soup For The Soul'?
I'm not sure that I give a toss
I've got chicken soup for my bowl

I'm eating it this morning
Though I made it yesterday
It's been in the fridge overnight
It tastes better next day anyway

I added in some chili sauce
Then threw some pasta in the pot
Then a little bit more chili sauce
Man, this soup's going to be hot!

Home-made soup is where it's at
Canned soup is one big con
My mouth is starting to burn now
My arse is going to hurt later on
