Soak the brown rice noodles in a bowl of very hot water for 10-15 minutes until tender but firm, then drain and set aside.
In a small bowl, whisk together the tamari, fish sauce, lime juice, and honey to create the Pad Thai sauce.
Heat the avocado oil in a large wok or skillet over medium-high heat.
Add the minced garlic and red pepper flakes to the pan, sautéing for 30 seconds until the aroma is released.
Add the shrimp to the skillet and cook for 2-3 minutes until they turn pink and are just cooked through.
Push the shrimp to one side of the pan and crack the egg into the empty space, scrambling it quickly until fully set.
Add the drained noodles and the prepared sauce to the pan, tossing vigorously to coat every strand.
Fold in the bean sprouts and cook for an additional minute until they are slightly softened but still retain a crunch.
Remove from heat and serve immediately, garnished with sliced green onions and crushed peanuts.
