Unfortunately - when you put too much of anything (salt, pepper, chilies, garlic, vinegar, etc) into a dish all you can do to salvage it is to dilute it ... and if you got really heavy handed that could be a lot to tame it down!
I agree with Saraaaaa ... you can certainly dilute your soup with a big dish of rice.
