This is a very common Holiday meal. I'll walk you through starting at the bottom left and spiral in.
The brown mush are sweat potatoes/yams depending on where you are from. Above that is a slice of processed turkey, similar to what you would get in a tv dinner. Under neath are instant stuffing, and maybe mashed potatoes with gravy if the jail is particularly generous. At the top is the condiment tray with salt and pepper. We have the vegetable of the day being corn in the top right (sometimes this can be carrots,or mixed vegetables). Under the corn is our bread rolls. These are pretty generic white bread in this tray but sometimes its just a hamburger bun or slices of sandwich bread. In the second condiment tray a pat of butter, and in the center is a slice of pie atop some cranberry sauce..
Grim isnt it? Dont do crime kids.
(Different jail, similar type thanksgiving tray, albeit I think put together with more care. No vegetable instead cranberry sauce and mixed fruit. and maybe cream under the pie)
