Soak brown rice noodles in hot water for 20-30 minutes until softened but still firm (al dente), then drain.
In a small bowl, whisk together tamarind paste, fish sauce, honey, and red pepper flakes to create the sauce.
Heat 1 tablespoon of oil in a large wok or skillet over medium-high heat.
Add sliced chicken and sauté until cooked through and slightly browned, approximately 5-7 minutes; remove chicken and set aside.
Add remaining 1 tablespoon of oil and minced garlic to the wok, sautéing for 30 seconds until fragrant.
Push garlic to the side, pour in beaten eggs, and scramble until just set.
Add drained noodles, cooked chicken, and the sauce mixture to the wok.
Toss continuously over high heat for 2-3 minutes until noodles are evenly coated and tender.
Stir in bean sprouts and green onions, cooking for an additional 1 minute.
Garnish with crushed peanuts, cilantro, and lime wedges before serving.
