matching single key/value pair to dictionary

I've got an NSMutableArray wherein every object is an 
NSMutableDictionary.  I would like to remove any NSMutableDictionary 
that contains (among other things) a given single key/value pair.

Is there an existing class/method that will let me accomplish this? 
I looked into using NSArray's makeObjectsPerformSelector but it 
didn't seem to fit my needs exactly.

thanks!
