12 slices French bread, sliced on the diagonal into 1/2-inch thick slices
12 thinly sliced pieces Serrano ham
12 thinly sliced pieces Manchego cheese
Whole grain mustard
Preheat grill. Brush each slice of bread on one side with olive oil and grill, oil-side down until lightly golden brown. Turn over and divide cheese among bread slices. Top each slice of cheese with the slices of ham and grill until the cheese begins to melt. Serve with the mustard.
