Cook the noodles according to package instructions. Rinse with cold water and set aside.
In a pan, sear bok choy cut side down in a little sesame oil until golden. Remove and set aside.
In the same pan, sear gyoza on one side until crisp.
Add a splash of water, cover, and steam for 3–4 minutes. Remove lid and let the bottoms crisp again.
Make the sauce by whisking almond butter, soy sauce, sesame oil, grated ginger, and a splash of warm water until smooth and vinegar too.
Toss noodles in sauce, plate them, top with bok choy and gyoza.
Garnish with chopped scallions, sesame seeds, chili crisp, or lime wedges.
