Cook soba noodles according to package directions, drain, and set aside.
In a small bowl, whisk together tamarind paste, fish sauce, and honey to create the Pad Thai sauce.
Heat avocado oil in a large skillet over medium-high heat and sauté minced garlic until fragrant.
Add shrimp to the skillet and cook until pink and opaque, then push them to one side.
Crack the egg into the empty side of the skillet, scramble until set, and then mix with the shrimp.
Toss in the cooked noodles, bean sprouts, and the prepared sauce, stirring constantly to coat everything evenly.
Fold in sliced green onions and red pepper flakes, then remove from heat.
Serve immediately topped with crushed peanuts and a fresh lime wedge.
