Rinse the pre-cooked udon noodles under warm water to loosen the strands, then drain and set aside.
Heat sesame oil in a large skillet over medium-high heat and add the peeled and deveined shrimp, seasoning with sea salt and black pepper.
Sear the shrimp for 2 minutes per side until pink and opaque, then remove from the pan and set aside.
In the same skillet, add the minced garlic, grated ginger, and chopped bok choy, sautéing for 2 minutes until the greens are slightly wilted.
Stir in the udon noodles, shelled edamame, coconut aminos, and chili crunch, tossing for 1-2 minutes to heat through.
Remove the skillet from the heat and fold in the Greek yogurt until a creamy sauce forms and coats the noodles.
Return the shrimp to the pan, garnish with sliced green onions, and serve immediately.
