im 100% Italian, Half Sicilian and we never had Brussels sprouts growing up. My Irish husband however..Speaking of original, I died when someone made Brussel sprouts without tagging trashy and she went crazy saying they stole her recipe. Because it was so soooo original. Take several seats tray.
You did not invent brussel sprouts and fake parmesan cheese , which by the way no true Sicilian uses that.
