When I was cooking large quantities of stews I used to add pearl barley, as the children got older they were quick to tell me, they never liked it, yet they like lentils, they could be the beans and legumes being spoken of on the Food Program, chick peas. I think, if you regularly cook huge beef stews and your family like it, don't change it. I see some stores here in Ireland have a made up 'soup mix' of pulses, maybe you could look at something like that. You can get the chick peas in tins now, years ago I use to have to soak them overnight.
