Parrots and giant tortoises immediately come to mind.

At a casual glance, there are animals with high bite forces in all of the major 
categories of feeding (i.e. herbivory, carnivory, omnivory).  While bite force 
adaptations give some idea of food preference within each category, I'm not 
sure they say anything about a preference for meat over vegetation.
