Way back in 1975, I was invited to my newly wed sister in law's home for home made chili. She excitedly told me she was using my Chili recipe. Well, it was so much better than mine! I asked if she followed my recipe to a tee or had she added something? Blushing, she said "I didn't have any tomato sauce so I used tomato soup. And that folks is why my Chili has been made with tomato soup since 1975. :)
Use your Chili recipe just replace the tomato sauce with undiluted tomato soup. It really allows your other flavors to come through. I won't use anything other than undiluted tomato soup when preparing my Chili.
