There are 3 views on chili whose proponents argue their position with a fervor usually reserved for religions and political parties.
Texas Chili is considered by many to be the only true chili. This is the one you go to if you want to win a chili cook-off. When I first moved to Texas I was informed in no uncertain terms that "there ain't no beans in chili". This recipe works well and has won a Chili Cook-off for me, in Texas.
Midwest Chili (bean soup to Texans) is what we ate while growing up in Ohio and, I assume, other parts of the Midwest. It's quick and good and a delight on a chilly autumn evening.
The other view mixes any kind of liquid with any kind of meat with any kind of bean. White Chili and Green Chili are examples of these oddities. While I like these, they are more useful as a surprise than as a mainstay. If you take either of these to a chili cook-off, the ladies will love you and the gourmets will think you are hip, but the men won't talk sports with you, which might be a good thing.
