Place the brown rice noodles in a large bowl and cover with very hot water, soaking for 8 to 10 minutes until tender but firm, then drain and set aside.
In a small jar, whisk together the tamari, fish sauce, tamarind paste, honey, and red pepper flakes until the sauce is smooth and combined.
Heat the sesame oil in a large wok or skillet over medium-high heat, then add the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Add the shrimp to the wok and cook for 2 to 3 minutes until they turn pink and opaque, then push them to one side of the pan.
Crack the egg into the empty side of the pan, scrambling it quickly with a spatula until just set before mixing it in with the shrimp.
Add the drained noodles and the prepared sauce to the pan, tossing everything together for 1 to 2 minutes until the noodles are well-coated and heated through.
Fold in the mung bean sprouts and sliced green onions, then remove from heat and serve immediately topped with crushed peanuts and a fresh lime wedge.
