Soak the brown rice noodles in a bowl of very hot water for 8-10 minutes until tender but firm, then drain and set aside.
In a small jar, whisk together the tamari, fish sauce, lime juice, and red pepper flakes to create the zesty Pad Thai sauce.
Heat the avocado oil in a large wok or non-stick skillet over medium-high heat.
Add the shrimp to the skillet and sear for 2 minutes per side until pink and opaque, then remove the shrimp and set aside.
In the same skillet, add the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Toss in the shredded carrots and bean sprouts, stir-frying for 1-2 minutes until slightly softened but still crisp.
Push the vegetables to the side of the pan, crack the egg into the empty space, and scramble until just set.
Add the drained noodles and cooked shrimp back into the pan, pouring the sauce over everything.
Toss vigorously for 1-2 minutes until the noodles are well-coated and the sauce has thickened slightly.
Remove from heat and garnish with sliced green onions, fresh cilantro, and crushed peanuts before serving.
