Yes Taco Soup and Chili really are the exact same thing.
In some places they call Chili Taco Soup and in most other places like the United States we call Taco Soup Chili.
But Taco Soup and Chili are the same thing.
If you've ever eaten Chili then really you've eaten Taco Soup.
When I eat chili or taco soup I like to make some cut up potatoes and then deep fry the potatoes and then put the potatoes that I've deep fried in a bowl.
Then I like to pour the taco soup or chili over the potatoes.
The addition of those fried potatoes makes the taco soup or chili that much better.
