Sentence ending で in じゃあ、僕はチーズバーガーで


> はじめ：まずは腹ごしらえしておこうよ。  
>  たもつ：じゃあ、僕はチーズバーガーで。

Here is で in the second line part of a contraction Japanese use in their daily
speech? If so what is the textbook version of the sentence?

Context: Hajime and Tamotsu are at a fast food restaurant, and the second line
should be Tamotsu giving his order to the shop assistant. Thus I think
で腹はらごしらえする may not be the best fit for the context...




As the dialog gives us no other clues what たもつ really had in his mind, I think
「僕はチーズバーガーで[腹]{はら}ごしらえする／腹ごしらえしておく」 would be the most logical expansion.
