This is Southwest comfort food from Arizona. I didn't know until I moved here how much better dried beans are than canned and how fast they are to soak following tip provided in the directions. I was also introduced to the wonderful flavors of fresh cilantro and Hatch chilies. Genuine Hatch chilies are from Hatch, New Mexico, and can be found fresh here only once a year, roasting in grocery store parking lots. Ohhh they smell so good! But you can get them canned in a lot of grocery stores and they still have that very unique, special flavor. You can substitute jalapeños if you can't find Hatch chilies. I put canned chicken broth in the recipe ingredients but usually use a cup of my own very rich homemade stock and add an extra cup of water. I err on the side of "not-too-hot" because I'm a wimp, but serve extra chilies on the side. The soup freezes very well, but eat the potatoes before freezing. Good with warm, buttered corn tortillas or corn bread. This is my own made-up recipe. Hope you enjoy it as much as we and our guests do!
