Reddit reviews Vegan Pressure Cooking: Delicious Beans, Grains and One-Pot Meals in Minutes

got a few facebook groups on this topic if you're into it I can send you links or add you.

check out "New Fast Food" by Jill Nussinow
I preordered it from her last year. I think she just came out with a new book too.
here's her blog "the veggie queen"

Also I think JL Fields "Vegan Pressure Cooking" is a great cookbook.
http://www.amazon.com/Vegan-Pressure-Cooking-Delicious-One-Pot/dp/1592336442
the kindle version is on sale for 2.99. it's a no brainer.

I don't have a pressure cooker, but I got this book Vegan Pressure Cooking by JL Fields for a friend and she loved it.
