Place the brown rice noodles in a large bowl and cover with very hot water; soak for 10-15 minutes until tender but firm, then drain.
In a small jar, whisk together the tamari, lime juice, fish sauce, honey, and red pepper flakes to create the Pad Thai sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat. Add the minced garlic and cubed tofu, sautéing for 2 minutes until the tofu begins to golden.
Add the shrimp to the skillet and cook for 2-3 minutes until they turn pink and opaque.
Push the shrimp and tofu to one side of the pan and crack the egg into the empty space; scramble quickly until just set.
Add the drained noodles and the prepared sauce to the pan, tossing everything together for 1-2 minutes until the noodles are well-coated and heated through.
Fold in the bean sprouts and green onions, cooking for just 30 seconds to maintain their crunch.
Garnish with crushed peanuts and fresh cilantro before serving with an extra lime wedge if desired.
