Preheat the oven to 375°. Arrange the bread slices on a large baking sheet and bake for 6 minutes, until toasted.
Meanwhile, in a small skillet, melt the butter. Add the garlic and season with salt and pepper. Cook over moderately low heat until the garlic is golden, about 2 minutes. Stir in the parsley. Spoon the garlic butter over the toasts and serve right away.
