Dong some reading as well as what I learned from family, it is pasta "Whores Style". Ok....I didn't know that prostitutes were known for their cooking. But check out Wiki for some interesting reading.
I use to think of it as what was in the refrigerator just thrown together. You know like a bunch of left over stuff sauteed in a pan then tossed with pasta. After a while it became more standardized with these ingredients.
