LOL - and you thought "Extra Hot" ment what?
About all you can do is "dilute" ... make another batch of soup and leave out the Rotel - and add it to the original batch to dilute it (only half as hot). You could also make a batch of black beans (1 pound dry weight) and some rice to dilute it ... if you live in Miami you might invite some Cuban friends over, they would probably love it just the way it is.
