Place the brown rice noodles in a large bowl and cover with very hot water, soaking for 8-10 minutes until tender but firm, then drain and set aside.
In a small jar, whisk together the lime juice, tamari, chili garlic sauce, and maple syrup to create the zesty pad thai sauce.
Pat the shrimp dry with paper towels and season lightly with sea salt and black pepper.
Heat the toasted sesame oil in a large wok or non-stick skillet over medium-high heat until shimmering.
Add the shrimp to the wok and sear for 2 minutes per side until pink and opaque, then remove the shrimp and set aside on a plate.
In the same wok, add the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Toss in the shredded carrots and mung bean sprouts, stir-frying for 1 minute to maintain their crispness.
Add the drained noodles and cooked shrimp back into the wok, then pour the sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce has thickened slightly and coated every noodle.
Divide the pad thai into bowls and garnish with sliced green onions and crushed roasted peanuts before serving hot.
