Prepare the brown rice noodles by soaking them in hot water for 8-10 minutes until tender but firm, then drain and set aside.
In a small bowl, whisk together the tamari, coconut aminos, lime juice, and red pepper flakes to create the savory pad thai sauce.
Heat the sesame oil in a large skillet or wok over medium-high heat, then add the shrimp and a pinch of sea salt, searing until pink and opaque.
Push the shrimp to one side of the pan, crack the egg into the empty space, and scramble it quickly until just set.
Add the minced garlic, grated ginger, and chopped green onions to the pan, sautéing for 1 minute until the aromatics are fragrant.
Toss in the cooked noodles and bean sprouts, pour the sauce over everything, and stir-fry for 2 minutes until the noodles are well-coated and steaming.
