Place the dry brown rice noodles in a large heat-proof bowl and cover with very hot water, soaking for 8-10 minutes until tender but firm, then drain.
In a small mixing bowl, whisk together the tamari, fish sauce, honey, and lime juice to create the Pad Thai sauce.
Heat the sesame oil in a large wok or non-stick skillet over medium-high heat.
Add the minced garlic and grated ginger to the wok, sautéing for 30 seconds until fragrant.
Add the shrimp to the wok and cook for 2-3 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 and scramble quickly until just set.
Add the drained noodles, the prepared sauce, and the mung bean sprouts to the wok.
Toss everything together vigorously for 1-2 minutes until the noodles are well-coated and the sprouts are slightly wilted.
Remove from heat and stir in the sliced green onions.
Serve immediately topped with crushed peanuts and red pepper flakes for a touch of heat.
