Place the dry brown rice noodles in a bowl of very hot water and soak for 8-10 minutes until tender but still firm, then drain.
In a small jar, whisk together the tamari, lime juice, honey, and red pepper flakes to create the pad thai sauce.
Heat the avocado oil in a large wok or skillet over medium-high heat and add the minced garlic and shrimp.
Sauté the shrimp for 2-3 minutes until they turn pink and opaque, then push them to one side of the pan.
Crack the egg into the empty side of the pan, scramble it quickly until set, and then mix it with the shrimp.
Add the drained noodles and the prepared sauce to the pan, tossing everything together for 1-2 minutes until the noodles are well coated.
Fold in the fresh bean sprouts and sliced green onions, cooking for just 30 seconds more to keep the sprouts crisp.
Plate the noodles and top with crushed roasted peanuts before serving.
