You have found my favorite appliance/pot/whatever you want to call it! I call it MY version of a microwave.
My cookbooks are at home and for the life of me I can't remember the name of my favorite one - but it's by Lorna Sass. But there are a LOT of good recipes on the web. One of our members is missvickie and her website is Miss Vickie's Pressure Cooker Recipes
Also, just Google Pressure Cooker Recipes.
I LOVE, LOVE, LOVE my pressure cooker. Let us know if you run across any spectacular recipes.
