Prepare the brown rice noodles according to package instructions by soaking them in hot water until tender but firm, then drain and set aside.
In a small bowl, whisk together the tamari, lime juice, fish sauce, honey, and red pepper flakes to create a vibrant, balanced sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat, then add the minced garlic and shrimp, sautéing until the shrimp are pink and opaque.
Push the shrimp to one side of the pan, crack the egg into the empty space, and scramble it quickly until just set.
Add the cooked noodles and the prepared sauce to the skillet, tossing everything together for two minutes until the noodles are well-coated and steaming.
Fold in the bean sprouts and sliced green onions, then serve immediately topped with crushed peanuts and fresh cilantro.
