Preheat oven to 350 degrees F.
Slice baguette into 1/2-inch thick slices and place on a baking sheet. Bake until toasted and golden, about 5 to 10 minutes.
Combine all remaining ingredients in a mixing bowl and mix thoroughly.
Top each toasted baguette slice with about 1 tablespoon of the tuna salad.
