How to Make It
Heat oven to 400° F. Place the baguette slices on a baking sheet and brush both sides of the bread with 2 tablespoons oil. Bake until golden brown, 4 to 5 minutes per side.
In a medium bowl, toss together the fennel with the orange juice and zest and the remaining 1 tablespoon of olive oil; season with ¼ teaspoon each salt and pepper.
Dividing evenly, top the toasted baguette slices with the salami and fennel mixture; sprinkle with the fennel fronds
