I started doing it this way because I like easy and I love the way the rice soaks up all the flavor when I do it all together. I found a basic recipe online and have been just playing around with variations on that.
Recently I used kidney beans instead of black beans and they were really good. Unfortunately, it wasn’t as easy because I had to pre-cook the kidney beans to work in the recipe, but it came out really tasty. That took an extra pressure cook (5 min) and natural release.
