🥛Milk🌾WheatSwaps and substitutions
For dairy-free, swap the béchamel and cheese for plant-based versions, or use a savory dairy-free spread with a little extra seasoning. For gluten-free, use gluten-free buns and a gluten-free thickener instead of flour; a gluten-free stock option also keeps it friendly for wheat-free diets.
What to serve with it
Serve with a crisp green salad or simple tomato salad to cut the richness, and add pickle spears or roasted potatoes for a fuller plate. A light beer, dry cider, or sparkling water with lemon also works well.
