pablum

A cereal brand for infants made from wheat, oat and cornmeal; a diet that does not require chewing.

And thus: Anything overly bland or simplistic, especially speech or writing.

If there had been a lesson in the execution for Unk’s squadmates, they were finding the lesson as digestible as Pablum.
