Follow these simple steps to create your Cranberry Apple Brie Crostini:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Bread: Slice the baguette or ciabatta into ½-inch thick slices. Arrange them on a baking sheet.
3. Brush with Olive Oil: Lightly brush each slice with olive oil on one side.
4. Toast the Bread: Place the baking sheet in the oven and toast the bread for about 10 minutes, or until golden brown.
5. Prepare the Topping: While the bread toasts, combine the cranberries and honey in a small saucepan over medium heat. Cook until the cranberries begin to burst, about 5-7 minutes. If using whole cranberries, mash them slightly with a fork.
6. Add Apples: Stir in the sliced apples and cook for an additional 2-3 minutes until heated through. Season with salt and pepper to taste.
7. Assemble the Crostini: Remove the toasted bread from the oven. On each slice, layer a slice of Brie cheese followed by a spoonful of the cranberry-apple mixture.
8. Garnish: If desired, sprinkle chopped fresh rosemary on top for added flavor.
9. Final Heat: Return the assembled crostinis to the oven for an additional 2-3 minutes, or until the Brie is slightly melted.
10. Serve Warm: Once done, remove from the oven and serve warm.
