Place the brown rice noodles in a bowl of very hot water and soak for 10-15 minutes until softened but still firm, then drain and set aside.
In a small jar, whisk together the tamari, lime juice, fish sauce, monk fruit sweetener, and red pepper flakes to create the Pad Thai sauce.
Heat the sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Add the shrimp to the pan and cook for 2 minutes per side until pink and opaque, then push them to one side of the skillet.
Crack the egg into the empty side of the pan and scramble quickly with a spatula until just set.
Toss in the drained noodles and the prepared sauce, stirring constantly for 1-2 minutes until the noodles are evenly coated and the sauce has thickened.
Fold in the bean sprouts and sliced green onions, cooking for just 30 seconds to maintain their crisp texture.
Serve immediately topped with crushed peanuts and an extra squeeze of lime if desired.
