Birkat HaMazon: Eating for Mezuman

Say birkat ha'mazon as a mezuman if:
  • You don't have enough men for a minyan (see above), AND
  • Two men wash, said ha'motzi, and ate bread, AND
  • One or more other men ate any food other than water and salt.
Note If the three men's eating overlapped in time with each other, they MAY say birkat ha'mazon with a mezuman. 
If the three men began eating at the same time, they MUST say birkat ha'mazon with a mezuman.
