riddle: after he ate all the flatbread, how much was left?

Watching you ignore the bowl of dal
Curries just don't interest you at all
Smears of gravy never stain your face
You ate it all, and barely left a trace

You ain't heard a single word I've said
All i want's a steamy piece of bread
Served fresh from the fiery tandoor
To soak the dregs of my lamb vinda—

Why do you get all the naan in the world?
Why do you get all the naan in the world?

All the oval flatbreads disappear
Lonely, charred flakes all that's left, i fear
Rice can't fill the desperate void i feel
You took it all, you make me want to—

Why do you get all the naan in the world? [x19]
Why do you get all the naan?
