Saucy in this case probably means classy. Like Pasta. With the broccoli must mean pot. So Action Bronson stays classy while still being a stoner, which may seem unheard of, but hey, who is gonna stop him? Saucy could also mean intoxicated, but the previous line makes me think classy
Furthermore, Action Bronson was a noted chef prior to getting into the rap game, and prepping and consuming of gourmet meals are a common theme in many of his tracks.
