Tofu noodles pick up the flavor of anything you mix with them. My personal opinion; Spaghetti cut Shirataki have the best texture, closest to the real deal. How low carb it ends up depends entirely on what you add. Here I use chive flavored cream cheese and tossed in leftover salmon.
I nuke the noodles for two minutes, then mix other ingredients and nuke again for a minute. You can find these noodles (also in angel hair) at HEB, Whole Foods, Sprouts, etc. They last in fridge forever.
Take care,
