Soak the brown rice noodles in a bowl of very hot water for 8-10 minutes until tender, then drain and set aside.
In a small glass jar, whisk together the tamari, fish sauce, lime juice, maple syrup, and red pepper flakes to create the sauce.
Heat the toasted sesame oil in a large non-stick skillet or wok over medium-high heat.
Add the shrimp to the skillet and sauté for 2-3 minutes until they turn pink and are just cooked through.
Toss in the shredded carrots and bean sprouts, stir-frying for 1 minute until they are slightly softened but still maintain a crunch.
Add the drained noodles and the prepared sauce to the skillet, tossing constantly for 1-2 minutes until everything is evenly coated and steaming hot.
Remove from heat and stir in the sliced green onions.
Transfer to a plate and garnish with crushed peanuts, fresh cilantro, and a lime wedge for squeezing.
