Tips & Substitutions
For a lighter version, you can substitute the reduced-calorie margarine with olive oil. If you prefer a different flavor, try adding garlic or shallots to the sauté. Use fresh green beans if available, or substitute with another vegetable like asparagus. To boost the dish's nutrition, consider adding spinach or kale. Make sure to stir the mixture continuously after adding the milk to prevent lumps.

Serve Au Gratin Fish Supreme over toasted muffin halves for a delightful texture contrast. Pair it with a fresh green salad or steamed vegetables for a balanced meal.

Storage & Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place in a microwave-safe dish and cover with a damp paper towel to keep moisture. Heat on medium power, stirring occasionally, until warmed through. Alternatively, reheat in a skillet over low heat until hot, adding a splash of milk if the mixture seems dry.
