Carson Dyle's recipe isn't bad. Sometimes I'll use canned beans, sometimes dried. There is a distinct difference in taste and texture, but convenience matters too.
I'd prefer to go with lean ground beef. Depending on the sodium in the canned tomatoes, I might add some. If I am using tomatoes from my garden, I'd definitely add salt. I'd probably add some herbs, like tarragon or thyme. Also, I like a sweeter taste. I'll add brown sugar to the mix. I sometimes squeeze in some lemon, if one is hanging around.
Using potatoes is not something I do, but it doesn't sound horrible either. My preference to serve the chili on a plate of rice, which makes a very filling meal.
Also, I make bigger batches for very little more work. That way you can freeze future meals in containers.
