What is a chuckwagon sandwich?

I’m sitting here enjoying a chuckwagon biscuit that one of my coworkers bought at a local grocery store deli.

I have eaten this “meat” since I was a child, it being a regular on the elementary school menus, and a staple at any small town deli or diner in the South.

I finally wonder: What the heck is this stuff?

A brief Google search turns up nil.

It’s beef - a breaded hamburger patty or cube steak.

Chuckwagon sandwich? This Southerner’s never heard of it. Sounds good, though.

Gamahuche. Does the meat resemble the breaded hamburger patty/cube steak that yabob suggested, or does it resemble the end-result of a pot roast–chuckroast or any such stringy beef, cooked over moist heat for a long time?

It is a breaded, processed patty, but the meat is whitish, resembling processed chicken.
The flavor is rather indeterminate, hence my question.
Tasty, though.

I’ve always assumed it’s an even nastier mass produced chicken fried steak type thing.

I hate them.
