In a bowl, flake the tuna with a fork. Add the fresh cream, mustard (if used), shallot (or red onion), sliced olives, diced tomato (if used), salt, pepper, and a few herbs. Mix well to obtain a homogeneous preparation.

Cut the baguette in half lengthwise, then each half in two widthwise to obtain 4 pieces. Slightly hollow out the crumb if you want a crispier result. Place the pieces on a baking tray lined with parchment paper. Lightly drizzle the bread slices with olive oil.

Spread the tuna mixture generously on each piece of baguette. Then sprinkle with grated cheese for a golden and stringy layer.

Bake in the oven for 10 to 15 minutes, until the cheese is melted, golden, and slightly crispy. Keep an eye on the cooking.

As soon as it comes out of the oven, serve immediately with a small green salad for a complete and balanced meal.

- For an even crispier texture, lightly toast the baguette under the grill before adding the topping.
- Flavor variation: Add a few capers, a bit of Espelette pepper, or lemon zest to the filling.
- Cheese variation: Replace the grated cheese with fresh goat cheese or parmesan shavings.
- Vegetable variation: Add grilled peppers, zucchini, or marinated artichokes to enrich the filling.
- Storage: This dish is best prepared and consumed immediately. You can store the ingredients separately and assemble just before serving.
