Prepare the brown rice noodles according to package instructions by soaking them in hot water until tender, then drain and set aside.
In a small bowl, whisk together the tamari, fish sauce, honey, lime juice, and red pepper flakes to create the stir-fry sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the shrimp to the skillet, seasoning with sea salt and black pepper, and cook for 2 minutes per side until pink and opaque.
Push the shrimp to one side of the pan and crack the egg into the empty space, scrambling it quickly until just set.
Add the minced garlic and the white parts of the green onions, sautéing for 30 seconds until fragrant.
Toss in the cooked noodles, bean sprouts, and the prepared sauce, stir-frying for 1-2 minutes until everything is well-coated and heated through.
Garnish with the remaining green onions and crushed peanuts before serving.
