I use my pressure cooker for everything from breakfast (3 minute steel cut oats) to dessert (winter fruit compote and more) and everything in between.
I am a pressure cooking expert, teacher and enthusiast - so much so that I have written a book about it, The New Fast Food: The Veggie Queen Pressure Cooks Whole Food Meals in Less than 30 Minutes.
My first pressure cooking experience more than 15 years ago was making lentil soup for my son which resulted in Shane's Fabulous Lentil Soup. I just never stopped.
You can find some recipes on my blog

I hope that this helps,
Jill aka The Veggie Queen
