Iceberg Lettuce

What vegetable leviathan
extends beneath the dinner table,
an unseen, monstrous green that pulls
the chair out from under our faith
 
in appearances: see a mere tuft
of leaf on the plate like a wing,
but if it flies away, it undoubtedly
will disturb the continental drift
 
asleep under the salad plate,
the hidden world we forget
as we reach for the smaller fork—
(and now, mouth full, don't speak: politely
 
chew your leaf of firmament
that's torn and tossed up in vinegar here as
we'll be tossed before its vast
root maybe someday or any moment).
