"test pasta made out of flour from dried ground bananas, egg whites, water and guar and xanthan gums, which add firmness and elasticity."

Or you could just skip the additives and make fried plantains or patacóns. Or eat rice pasta, I suppose I don't miss pasta very much though. I'll take crunchy fried plantains over pasta any day.

I think one of the goals of eating paleo (or in any healthy manner that you choose) should be to limit the amount of processed foods and eat as close to a whole food as possible at all times. This... this ain't that.

spaghetti squash or bust.

Sounds like it will cause more digestive woes than normal wheat pasta. This is because this pasta gets its texture from fructans (guar/xanthan gums and unripe banana fructans) rather than from protein (breads texture comes from amazing texture of the gluten protein). Since most people who think they are gluten intolerant are actually just intolerant to FODMAPs, which happen to be very prevalent in wheat, this pasta is likely to be far worse than normal pasta...
