An easy way of saying "I'm not hungry, but if you're cooking/buying me food I'm up for eating it."
"Hey I'm running to McD's, you want me to grab you something??" "Yeah, I could eat."

I Could Eat It
A phrase used to size up something; ie when talking about how small some new electronics are, the ability to eat them is descriptive of its small size.
Said first by Karl Pilkington- a fantastic idiot with a head like an orange- in conversation on The RickyGervais Show podcast about 'I'm a celebrity get me out of here' and a celebrity eating a kangaroo penis.
Ricky: "So what're you saying??"
Karl: "I'm saying...I could eat a knob at night."
