eat up a sandwich

(cheesy veggie toasted sandwich at SOUTH COAST DELI in Goleta)

I was always surprised that the portions of meal were so big
when I just stared living in SB.

Especially the size of hamburger combo, sandwiches, salads, steaks
in U.S. are almost twice than Japan.
So I could not eat them up.

Recently I feel that the size of my stomach gets bigger little by little,
because it's not impossible to eat up a hamburger combo,
a big sandwich and so on.

I suppose that I can't be satisfied with the Japanese size of meals.
