I guess if you call it a parfait or mousse and pay $3.00 for it then it's okay to be seen eating it.  The Food Police should have to buy her lunch where I work.  A PB&J from our dining service cost $4.99 and other sandwiches are $7.79 before tax.  Your entire lunch cost less than one of our sandwiches.  Don't really know what point she's trying to make.
