portion input wanted.

I like to do random things on the stove for neighbors.  I'm thinking a pot of minestrone for a family here and I measured my biggest pot, did the π r square thing and it came out to 1.72 gallons with barely enough room to stir. That works out to 14- 2 cup bowls, max.
They are a blended family with 9 kids, so 11 people.  Adolescent kids can eat a bunch.  Do you folks think this would be adequate with some nice crusty bread?
