Preheat oven to 425 degrees F (220 C). Bring a large stockpot of water to a boil. Lightly oil a 10-inch pie plate and set aside. Put the spinach in a large colander. Pour the boiling water over the spinach. Toss the leaves until they are all wilted. Press the spinach down in the colander until most of the liquid has been extracted. If your colander is not large enough, you may want to wilt half the spinach at a time. Transfer the spinach to a cutting board and coarsely chop it. Put the spinach in a bowl and sprinkle the flour over it. Stir well to combine. Stir in the broth, parsley, 1-2 Tbsp of olive oil, garlic, salt, and pepper. Transfer the spinach mixture to the prepared pie plate. Sprinkle it with the bread crumbs and drizzle it with olive oil. Bake for 20 minutes, or until the top is lightly browned and the mixture is sizzling. Serve hot.
