For an elevated spin on classic ham sandwich, top your next crostini with thinly sliced prosciutto (or ham), cream cheese spread, your favorite mustard-mayonnaise sauce, and chive sprigs for a fresh, open-faced toast that are perfect for entertaining.
Preheat oven to 375°F. Arrange baguette slices in a single layer on a baking sheet. Brush tops with melted butter. Bake in preheated oven until slices are just beginning to brown at edges, about 12 minutes. Remove from oven, and cool to room temperature.
