Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently with a splash of water to restore moisture.
Substitutions: For a gluten-free version, ensure your onion soup mix is certified gluten-free or use a homemade blend of dried onions, garlic powder, and herbs. You can also substitute bulgur with quinoa or couscous, adjusting cooking times accordingly.
Variations: Add a handful of fresh parsley or dill for extra freshness. For more protein, mix in cooked lentils or chickpeas.
