I kept forgetting to come and comment on this, Joe.
A very different take on things, I like the novelty. The centered composition works well, as does the black background. You've done a really good job arranging things, which sounds like a minor success but is really much more difficult to achieve than most think. Usually set-up shots look very manufactured and distinctly "wrong," but this looks very natural.
In regards to what others have said about the lighting, did you consider putting your camera on a tripod and using a longer exposure? Stop down to perhaps F7.1 or so and drop your ISO a little bit maybe, and then use a flashlight to light paint the scene? This will eliminate the harshness that was noted in the comments, and keep your shadows from being so directional, with more of an even soft light. Just sorta trial and error things, evenly "painting" the entire plate. I don't recall if your camera has RAW, but if so, shoot in raw and adjust your white balance after the fact. If not, do some experiements seeing which setting turns out the best result and use that (but don't use auto as you'll get variation). It may also have a custom setting, in which case you can set that, as well.
I love your idea, and the title makes it even better! I think actually getting some dip on a chip would help sell it even more. In fact this shot makes me long to see a drip of the dip dropping off of a chip.
