Soak rice noodles in hot water for 10-15 minutes until al dente, then drain.
Whisk together tamari, fish sauce, lime juice, maple syrup, tamarind paste, and red pepper flakes in a small bowl.
Heat avocado oil in a large skillet or wok over medium-high heat and add minced garlic.
Add sliced chicken breast to the skillet and cook until golden brown and cooked through.
Push chicken to one side of the pan and crack the egg into the empty space, scrambling until set.
Add the drained noodles, shredded carrots, and sauce mixture to the pan, tossing everything to combine.
Stir in bean sprouts and green onions, cooking for just one minute until the sprouts slightly soften.
Serve immediately topped with crushed peanuts for a satisfying crunch.
