Trader Joe's Harvest Grain Blend is a blend of Israeli couscous, orso, baby garbanzo beans and tiny red quinoa grains. Israeli couscous predominates. I don't remember how much it cost, but it was cheaper than the bags of pure Israeli couscous. Most importantly, my kids love it, and I think it's probably marginally more nutritious than the Israeli couscous by itself.
Though the instructions say to cook it with 1 Tbsp of butter ( I guess to make it more buttery), I always omit it without any adverse effects. I do the same with regular couscous and other grains, why have added fat if it's not needed? Once you have the water boiling, it cooks in 10 minutes. So it's a great and easy side for stews.
