Prep the shirataki noodles: drain both packages into a colander and rinse very well under cold running water for at least 60 seconds. Shirataki noodles have a natural odor from the konjac root packaging liquid - thorough rinsing removes it completely. Pat dry with paper towels. Using kitchen scissors, cut the noodles several times directly in the colander to shorten them to manageable lengths.
Dry-toast the noodles (optional but recommended): place rinsed, drained shirataki noodles in a dry skillet over medium heat for 2-3 minutes, stirring occasionally, until any remaining moisture evaporates. This step improves the texture significantly and helps the noodles absorb the dressing better. Remove from heat and let cool.
Make the dressing: whisk together lime juice, fish sauce, zero sugar honey, and avocado oil in a bowl until the honey is fully dissolved. Taste - it should be savory, bright, and slightly sweet with the fish sauce as the backbone. It will smell strong. In the finished salad it will be perfectly balanced.
Dress the noodles: place cooled noodles in a large bowl. Pour dressing over and toss well. Let sit 10 minutes - this rest time is what allows shirataki to absorb the flavor of the dressing.
Add shrimp and vegetables: add shrimp, cilantro, soybean sprouts, and red chili to the dressed noodles. Toss gently to combine.
Serve: divide into 4 bowls. Top each with chopped roasted peanuts and a lime wedge. Serve immediately or refrigerate up to 2 hours before serving.
