Alphabet Soup

Is the title of today's brain bender (from the handy dandy discount MENSA calendar). Ready to play?

---------------------

The 11 letters below can be anagrammed into a two-word slang expression for an item served in a school cafeteria or mess hall.

What is the item?

A E E M M R S T T Y Y

-----------------------

I think this particular lunch item may have seen it's day. But considering that they still occasionally have "chop suey" day at the girls school, maybe not.

Random thought - you 'spoze that S.O.S. would be considered a pretty completely politically incorrect lunch item in this day and age? Yeah - me too. Might offend those folks who actually DO eat sh*t, or whatever.

Anyway.... Like always the answer will be found later in the comments. Hope your lunch was a much yummier one!
