Preheat your oven to 400 degrees F.
Slice off the top quarter of your ciabatta bread (reserve top to make breadcrumbs or croutons).
Combine melted butter, garlic, Kosher salt & black pepper. Mix well and allow it to sit for 5 minutes or so.
Liberally coat the top of your bread with the butter-garlic mixture.
Place the bread on a baking sheet and bake for 6 minutes.
Remove the bread from the oven, sprinkle with 1/2 the parsley, followed by the olives and then return it to the oven for 4-5 minutes or until bread is crisped on the perimeter yet still soft in the middle.
Sprinkle loaf with Feta, and remaining parsley.
Shake some Greek seasoning over-top.
Drizzle with your oil/seasoning mixture (which you can whip up while bread is baking), slice and serve.
