Soak the brown rice noodles in hot water for 8-10 minutes until tender, then drain and set aside.
In a small bowl, whisk together the tamari, lime juice, and chili flakes to create the sauce.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the minced garlic and grated ginger to the skillet, sautéing for 30 seconds until fragrant.
Add the shrimp to the skillet, seasoning with sea salt and black pepper, and cook for 2-3 minutes until pink and opaque.
Push the shrimp to one side of the pan and crack the egg into the empty space, scrambling it quickly until just set.
Add the drained noodles and the prepared chili-lime sauce to the skillet, tossing everything together to coat thoroughly.
Fold in the bean sprouts and cook for 1 additional minute until they are slightly softened but still retain a crunch.
Remove from heat and garnish with sliced green onions and crushed peanuts before serving.
