Soak brown rice noodles in hot water for 10 minutes until tender, then drain and set aside.
In a small bowl, whisk together the tamari, fish sauce, lime juice, honey, and red pepper flakes.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the garlic and shrimp to the skillet, 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 until just cooked.
Toss in the noodles, bean sprouts, and sauce, stir-frying for 2 minutes until everything is well coated and hot.
Garnish with scallions and crushed peanuts before serving.
