12/31/2011 10:45 AM PST

Amber Portwood's second-to-last meal of 2011 won't be leaving her with fond memories ... but at least there will be KOOL-AID!!!

The "Teen Mom" star is currently behind bars at Madison County Jail in Indiana, awaiting her late January court date on possible probation violations. 

According to our sources, Portwood's lunch today will consist of a turkey sandwich on white bread with American cheese, fruit cocktail, and Kool-Aid to drink.

Portwood's Xmas dinner wasn't much better -- she dined on turkey sausage pizza, a side of carrots (cold, not steamed), peas and some pineapple.

If the food doesn't scare her straight, nothing will.
