Soak the brown rice noodles in hot water for about 10 minutes until they are tender but still firm to the bite.
In a small bowl, whisk together the tamari, fish sauce, maple syrup, and lime juice to create the Pad Thai sauce.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the minced garlic and cubed tofu to the skillet, sautéing until the tofu is lightly golden on all sides.
Add the raw shrimp to the pan and cook for 2 to 3 minutes until they turn pink and are just cooked through.
Push the shrimp and tofu to one side of the skillet, crack the egg into the empty space, and scramble it until fully set.
Drain the noodles and add them to the skillet along with the prepared sauce and red pepper flakes.
Toss all ingredients together for 1 to 2 minutes until the noodles are well-coated and the sauce has thickened slightly.
Fold in the bean sprouts and sliced green onions, stirring for just 30 seconds to maintain their crispness.
Remove from heat and serve immediately, garnished with crushed peanuts and an extra squeeze of fresh lime.
