Chef tips
If your mushrooms release a lot of liquid, let them rest for 2 minutes after cooking so the filling can set. For a more golden topping, lightly spray with oil before air frying.
Substitutions
You can replace the millet with cooked quinoa. Walnuts can be swapped for sunflower seeds if you want to avoid tree nuts, and parsley can be replaced with dill or chives. For a gluten-free version, use gluten-free breadcrumbs.
