Why it works

  • Celiac disease: The sauce is thickened with cornstarch and the onions are coated in rice flour, with gluten-free stock — nothing wheaty in the dish.
  • Dairy-free: Coconut milk makes the sauce creamy, so there's no milk, cream or butter anywhere in the dish.

Celiac check: watch for hidden gluten in soy sauce, stock, malt vinegar and seasoning blends, and oats that aren’t certified. Gluten gives food ideas, not medical advice: always check labels for allergens and cross-contact.
