The speaker was discussing an issue and wanted to get to the heart of the matter. This is a mash up of “get down to the nuts and bolts” (get down to the basic facts) and “everything from soup to nuts” (almost everything one can think of). “Get down to brass tacks” (begin to talk about the important stuff) might also be in the mix given the context. And then there is the Soup Nazi (nutsy?) who also wanted everyone to just get to the heart of the matter and order soup. A big thank you to Elaine Hatfield for hearing this one and passing it on!
