Prepare the brown rice noodles according to package instructions by soaking in hot water until tender but firm; drain and set aside.
In a small bowl, whisk together the tamari, fish sauce, lime juice, honey, and red pepper flakes to create the savory sauce.
Heat the avocado oil in a large wok or non-stick skillet over medium-high heat, then add the minced garlic and sauté 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, scramble it quickly until just set, and then toss it together with the shrimp.
Add the prepared noodles and the sauce to the wok, tossing everything vigorously for 1-2 minutes until the noodles are well-coated and heated through.
Fold in the bean sprouts and sliced green onions, cooking for just 30 seconds more to maintain their crisp texture.
Serve immediately topped with crushed peanuts and fresh cilantro for a bright and flavorful finish.
