This soup is simple, comforting and inexpensive. I make mine with homemade chili powder made from dried habaneros so mine is pretty spicy - if you are using a milder chili powder you might consider adding additonal cayenne pepper. You can also substitute cajun seasoning for the chili powder. You could also do this on the stovetop - just brown the hamburger add all the rest of the ingredients and simmer until the beans are tender.
