Preheat oven to 400 degrees & slice french bread loaf into thin slices, discarding the ends and placing them flat on a baking sheet.
Spray or drizzle slices with olive oil and sprinkle with a pinch of garlic salt. Bake until crispy - about 5-8 minutes.
While bread slices bake, slice brie into thin slices and half the proscuitto the long way, making two long strips of each.
Once crostini is done, remove from oven and let cool a few minutes. Line up on serving tray and begin assembly.
Place one slice of brie on top of each crostini, followed by a wrapped or folded piece of proscuitto.
Drizzle each with honey and top with walnuts. Serve immediately!
As far as measurements go, you can make as many or as few as you'd like, so base the amount of brie and proscuitto off of quantity. Remember, you are getting two for one on each slice of procuitto, so if you have five total pieces, you'll have ten halves to top with!
**You can easily bake the bread slices ahead of time and add toppings right before serving!
