Slice a loaf of Italian bread, stopping short of the bottom so the loaf stays intact. Melt 4 tablespoons butter with 1 tablespoon olive oil; add 2 to 3 minced garlic cloves and 1/2 teaspoon salt and cook, stirring, 2 minutes. Stir in 2 tablespoons chopped parsley. Spread the garlic mixture between the bread slices; wrap in foil and bake at 375 degrees F, 15 minutes. Unwrap and bake until crisp, 5 more minutes.
