In an attempt to sate your desire for even more sandwich-related tidbits (of the salmonella-free kind) after today's story on sandwiches, I turned to Harry Balzer of the market research firm NPD Group, the go-to person when it comes to what we, as a nation, eat.

The sandwich, Balzer says, has, for decades, been the No. 1 thing Americans eat. In a way, it's the last of its kind. "The sandwich requires your labor and assembly. And it in effect celebrates freshness and diversity," he says. "It's the No. 1 homemade dish in America."

Of course, that's changing. "At one point, 98 percent of all sandwiches eaten in our homes were prepared by someone in the home. Now that's about 90 percent," Balzer says. "Jimmy John's delivers."

And: Breakfast sandwiches have seen a sharp increase, too, he says.

Here's more, by the numbers.
