The answer is...

Gabriel! Gabriel ate his entire foot-long Subway sub roll while Adalia shoved about 4-5 fries in her mouth all at once and then threw them all up. Not surprisingly, she ended up in the bathtub and did not get to finish her meal. Here are some pictures of Gabriel finishing his meal. (Fortunately there are no pictures of Adalia throwing up her meal to be posted :) ).

Almost done

The last crumb
Finished!
