Bean, I just did a quick google search of vegan protein powders, and found loads of options that might work for you! (Vegan because it covers the casein and whey, and will more likely be made from alternative grains and nuts, thus avoiding soy and gluten.) Your DH might be able to find some in your local coop, even, if you don't want to wait for amazon!
You could try brown rice protein. See here: http://www.sunwarrior.com/store/protein-raw-vegan-vanilla.html
Ethelpea, great recipe!
BeanBean06, I was vegan for a few years and my BF at the time had a severe gluten allergy. We both worked at a health food store and tried EVERY protein/meal supplement within those parameters. The worst was a powder from split peas. By far one of the worst things I have ever tried to ingest, yuck! One the other side of the spectrum is the raw food vegan protein powder by Garden of Life. I highly recommend this powder because it also contains probiotic compounds and enzymes to increase your absorption of all the healthy vitamins and minerals it contains. I've mixed it with hemp protein at a 2:1 ratio for added Omegas and fiber. Coconut water is a great base if you don't want all the extra sugar in many fruit juices. The powder has a mild but earthy taste. I wouldn't sit around sipping on it for fun, but I've used it for months at time without developing an aversion to it like some of the other ones I've tried. There are no sweeteners or artificial flavorings added. So for my friends I add a little agave syrup and/or vanilla extract to the mix. Good luck! Midwife told me to aim for 120g of protein a day. Feels like I'm eating for a body builder!
