I just picked up a jar of this at our local supermarket. I added approx 1 lb of browned/ground beef and a can of black beans. It looked and smelled good but from the look of it I felt like added a cana of tomato paste & equal amt of water.  I loved the result. I think I do like my chili a little more tomato-y than some people, so you might be just fine w/o the addition of the paste. It was a little spicier than I ususally like, but not over the top, still very good. I served in a bowl with a piece of cornbread on top. Everyone liked it except my youngest daughter, (8yo), will make it again.
