Here is a great source of whey protein. They're out of the UK, and you need to sign up to order from them, but it's a really clean, cheap source of protein. I bought 4kg, which is about $75 retail, but if you google for a 15% off coupon, it takes it down to about $63, with shipping it ends up being $70 for 8.8 pounds of whey protein isolate, which is 90% protein. It ends up being as cheap as buying hamburger for $2 a pound without all the hormones, antibiotics, and other crap.
Beans, rice, and yogurt or kefir (since you're already making it yourself) is a really good protein combination. You can make mung or azuki beans and rice with vegetables, garlic, ginger. Top it with ghee, Bragg's and plain yogurt or kefir; it's a great flavor combination. Here's a sample recipe for a kitchari. Kitchari is basically any combination of beans and rice with vegetables with some Indian spices, and is used in ayurvedics. If you buy your beans and basmati rice at CostCo, it ends up being $15 for a 20 pound bag of rice and not much more than that for the beans.
