Soak the brown rice noodles in hot water for 10-15 minutes until tender but firm, then drain and set aside.
In a small bowl, whisk together the tamari, tamarind paste, honey, lime juice, and red pepper flakes to create the sauce.
Heat avocado oil in a large skillet or wok over medium-high heat and sauté the minced garlic for 30 seconds until fragrant.
Add the shrimp to the pan and cook for 2-3 minutes until pink and opaque, then push them to one side of the skillet.
Crack the egg into the empty side of the pan, scramble until fully set, and then toss together with the cooked shrimp.
Add the drained noodles and the prepared sauce to the skillet, stirring constantly for 1-2 minutes to coat everything evenly.
Fold in the bean sprouts and sliced green onions, cooking for just 30 seconds until they are slightly wilted but still crisp.
Transfer to a plate and serve immediately topped with crushed peanuts and an extra squeeze of fresh lime.
