That's a great question, and a tricky one! Certainly, you can use gluten-free oyster sauce for the filling (Lee Kum Kee makes a GF oyster sauce—look for the green panda label). However, when it comes to the wrappers, we do use wheat starch. Wheat starch is technically just the starch, isolated from the flour—with the gluten removed. This is likely fine if you have a gluten sensitivity rather than a serious allergy or Celiac's (though you should always consult a doctor first!). However, some products marketed as gluten-free do contain wheat starch, as long as the wheat starch is what's called "Codex" wheat starch, which has less than 20 ppm of gluten.
