3 tablespoons butter, room temperature
4 slices firm white sandwich bread
6 ounces Manchego cheese, thinly sliced
4 ounces thinly sliced jamón Serrano or prosciutto

Line baking sheet with waxed paper. Spread butter on bread slices, dividing equally. Place 2 bread slices on prepared baking sheet, buttered side down. Top bread slices with half of sliced cheese (1 1/2 ounces each); top cheese with ham, dividing equally. Sprinkle dates over. Top with remaining cheese, then remaining 2 bread slices, buttered side up. Refrigerate 30 minutes. DO AHEAD: Can be made 8 hours ahead. Cover with plastic wrap and keep chilled.
