Soak brown rice noodles in hot water for 10 minutes until al dente, then drain and set aside.
In a small bowl, whisk together the fish sauce, tamarind paste, and honey until smooth.
Heat avocado oil in a large wok or skillet over medium-high heat and sauté the minced garlic for 30 seconds.
Add the shrimp to the pan and cook for 2-3 minutes until pink and opaque.
Push the shrimp to one side of the pan, crack the egg into the empty space, and scramble until just set.
Add the soaked noodles and the prepared sauce to the pan, tossing everything together for 2 minutes.
Stir in the bean sprouts and green onions, cooking for 1 minute more until the sprouts are slightly wilted.
Serve immediately topped with crushed peanuts, red pepper flakes, and a fresh squeeze of lime.
