Boil the soba noodles for 4-5 minutes until tender, then drain and rinse with cold water to prevent sticking.
In a small bowl, whisk together the coconut aminos, fresh lime juice, and fish sauce to create the savory pad thai base.
Heat avocado oil in a large skillet or wok over medium-high heat and sauté the minced garlic until fragrant.
Add the shrimp to the skillet and cook for 2-3 minutes until pink and opaque, then push them to one side of the pan.
Crack the egg into the empty side of the pan, scramble until just set, and then mix it into the shrimp.
Toss in the cooked noodles, bean sprouts, and sauce, stir-frying for 1 minute until everything is well-coated and heated through.
Serve immediately topped with sliced green onions, crushed peanuts, and red pepper flakes for a hint of heat.
