If I was a guest in someone's home, minding my manners, and they had made the unfortunate mistake of putting mushrooms in chili, I suppose I could choke it down. But tofu? No way in hell. Watch the DUmmies put peas in the chili next.
North Carolina I had chili with corn added. Now this was in a place off the tar road and people came from miles around to eat that Chili. What ever was in season went into the pot, didn't matter what came from the fields in it went. [ did I mention this was a well known Biker Bar ] ?
Good hardy eaten, WTF these people were not from Texas and just wanted to fill up their belly as they had another 200 miles to go, in all weather, it was the spices that kept them stopping in on a round trip.
One can make Chili out of anything, any kind of meat and throw in darn near anything as long as there is the chili spices. Texas chili is of one kind but the rest of the nation has taken the original Texas chili and thrown in what is available to them, as long as you have the spices, even adding carrots and radishes, it is CHILI.
