Prepare the brown rice noodles by soaking them in very hot water for 8-10 minutes until tender but firm, then drain and set aside.
In a small bowl, whisk together the tamari, lime juice, chili paste, minced garlic, and coconut sugar to create the zesty sauce.
Heat the sesame oil in a large wok or non-stick skillet over medium-high heat, then add the shrimp and season with sea salt and black pepper.
Sauté the shrimp for 2-3 minutes until pink and opaque, then push them to one side of the pan.
Crack the egg into the empty side of the pan, scramble it until just set, then mix it into the shrimp.
Add the soaked noodles, bean sprouts, shredded carrots, and the prepared sauce to the pan, tossing everything together for 2 minutes.
Remove from heat and stir in the sliced scallions, then garnish with crushed peanuts before serving.
