Coming out of deep lurk mode with a bit of a puzzlement.

I have a dinner tonight where the theme is Peruvian food. I am
bringing one main dish (Huatia) and one appetizer, which is Ceviche.
According to most recipes I perused, this is traditionally served with
small ears of corn on the cob on a bed of lettuce, but as a pratical
matter, there will be (a) way too much food as it is, and (b) corn is
very out of season in my neck of the woods.

One thought was to serve it on the bed of lettuce alone, but somebody
suggested a flat bread. So I start looking and can't find any bread
recipes for Peru. I would have assumed that they would have
SOMETHING; I've never heard of a people that doesn't. I asked the
only folks I know who have spent time there, but they were so far up
in the Andes that they didn't know the Peruvians even ATE things like
Ceviche or beef. (On the other hand, they offered several recipes for
goat and guinea pig...)

So, what is it? Dinner is tonight, and I need to find something.

Thanks,

David
