A gourmand who zealously avoids all exercise as "seriously damaging to one's health," he had caviar for breakfast and was now having oysters for lunch, whetted with wine, as he fueled himself for a postprandial reading at the Montauk Club in Brooklyn.
-- Mel Gussow, "The Man Who Put Horace Rumpole on the Case", New York Times, April 12, 1995
When I wake up in the morning, I can have my usual breakfast -- a slightly bizarre concoction of three kinds of cold cereal topped with grapes and a cup of decaf -- and then stagger back to bed for a postprandial snooze.
-- Sylvan Fox, "It's Less Hectic Staying Put In One Place", Newsday, April 3, 1994
Postprandial is from post- + prandial, from Latin prandium, "a late breakfast or lunch."
