But apparently they're also important to Spaniards. Last night's couchsurfers are from southern Spain, and Jose commented that most Spaniards eat a small breakfast -- a little bread, fruit, maybe cheese -- certainly not huge piles of eggs and potatoes and meat. (This came up while we were eating Ziffy omelets at the Lincoln Street Diner, of course.)
I usually have a small breakfast, too, but apparently Spaniards tend to have a small sandwich or other snack later in the morning, before their big meal of the day early in the afternoon.
I have a feeling I would gain weight quickly if I started eating a snack between breakfast and lunch regularly.
