Place the dry brown rice noodles in a bowl of very hot water and soak for 8-10 minutes until tender but firm, then drain and set aside.
In a small glass jar, whisk together the tamari, lime juice, chili paste, and fish sauce to create the zesty Pad Thai sauce.
Season the shrimp with sea salt and black pepper.
Heat the sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the shrimp to the skillet and sauté for 2 minutes per side until pink and opaque, then remove the shrimp and set aside.
In the same skillet, crack the egg and scramble quickly until just set.
Add the shredded carrots and soaked noodles to the skillet, tossing with the egg for 1 minute.
Pour the prepared sauce over the noodle mixture and add the cooked shrimp and bean sprouts back into the pan.
Toss everything together for 1-2 minutes until the sauce is thickened and the sprouts are slightly wilted.
Garnish with sliced green onions and serve immediately.
