How to Make It
Using the end of a wooden spoon, gently enlarge the opening on each date to make it easier to fill. Carefully fill each date with about 1/2 teaspoon cheese.
Cut each slice of bacon crosswise into 3 pieces. (Reserve remaining bacon pieces for another use.) Wrap each date with 1 piece of bacon, making sure the bacon wraps completely around date.
Preheat grill to medium (350°F to 400°F). Place dates on grill rack coated with cooking spray; grill, uncovered, turning occasionally, until bacon is crisp and cheese is warmed, 6 to 8 minutes. Transfer grilled dates to a platter. Sprinkle with pistachios.
