Prepare the brown rice noodles according to package instructions until tender; drain and set aside.
In a small bowl, whisk together the tamari, fish sauce, honey, and lime juice to create the pad thai sauce.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the minced garlic and shrimp to the skillet, sautéing for 2-3 minutes until the shrimp is pink and opaque.
Push the shrimp to one side of the pan and crack the egg into the empty space, scrambling it until just set.
Add the cooked noodles, prepared sauce mixture, and red pepper flakes to the pan, tossing everything together to coat.
Fold in the bean sprouts and sliced green onions, cooking for 1 minute until the vegetables are slightly softened but still crisp.
Garnish with fresh cilantro and serve immediately.
