When circumstances took the family on the road, they’d grab the nuggets of portable soup – dissolving them in hot water, sprinkling in salt and cutting in whatever herbs and vegetables they could forage from the roadside.  In an instant, the traveler’s would have a meal – but unlike the instant meals of today, this was real food.
