Prepare noodles according to package instructions by soaking in hot water until tender, then drain.
In a small bowl, whisk together the tamari, lime juice, fish sauce, and maple syrup to create the sauce.
Heat the avocado oil in a large wok or skillet over medium-high heat.
Add the minced garlic, shrimp, and cubed tofu, sautéing until the shrimp is pink and the tofu is lightly golden.
Push the shrimp and tofu to one side of the pan and crack the egg into the empty space, scrambling it until just set.
Add the drained noodles and the prepared sauce to the pan, tossing everything together for 2 minutes to coat thoroughly.
Stir in the bean sprouts and sliced scallions, cooking for another 30 seconds until the sprouts just begin to soften.
Serve immediately topped with crushed peanuts and red pepper flakes for a spicy kick.
