Have you ever read a paragraph in a book that made your eyes tear up? Did you feel a knot forming in your throat as the emotions began to build up and did you feel your heart actually begin to break?
That was a "tasty" piece of work - one you could "really sink your teeth into", as the saying goes. 
When was the last time you, yourself, wrote that way? Of course, that's the way we strive to write each and every time the fingers touch the keyboard, pencil, or notepad on our cell phones. But I also know from experience that sometimes we kind of let our hair down and tap away for sheer word count, knowing that we have this amazing idea in our head that absolutely has to get into the written form before we lose it - and we know we can always go back in later to edit, refine, adjust later. That's what we do anyway!
So with this in mind, when we do get back in there for that edit, are we creating that tasty morsel for our readers?
One thing I like to do when I read other people's work is to picture myself in the situation; I like to hear the roaring waterfall, taste that piece of stale bread, feel the stone path under my feet as I walk alongside the characters. 
As an example, let's use Amy. 
She went to the fair today. She ate cotton candy. Amy finally got to ride the roller coaster. (18 words)
Amy's eyes scaled the iron giant, wiping sticky fingers across the front of her jeans. The screams coming from the roller coaster sounded more fun than anything else, she concluded, as the last bite of cotton candy entered her mouth. She allowed it to melt on her tongue for a second before tossing the empty spool in the trash can. (60 words)
We not only led the reader in a different direction that was more descriptive, but we even added more to our word count. More than tripled it.
When we are able to place our readers in those places and they don't have to imagine hearing that waterfall, but we actually lead them to it - we have done our job!
