This tastes just like a quiche - only better because it's CRUSTIER! (And much faster to make!). This freezes really well (once cooked). Wrap it in foil and you can pop it straight into the oven to reheat from frozen. The filling possibilities are endless! I've provided a few suggestions in the notes.
1. You could also make this with one long baguette. This recipe is very easy to scale up or down. You just need enough filling and egg mixture to fill the crevice in the bread.
2. The idea of this recipe is from these Baked Egg Boats
by Deliciously Declassified.
3. Other filling ideas: smoked salmon, ham, tinned salmon or tuna (drained), finely chopped olives, sundried tomatoes, artichokes, salami
4. Freeze after baking. If in foil, you can reheat in the oven from frozen. I recommend warming it up but it is also lovely at room temperature - just like a quiche!
