- 2 pounds lean ground beef
 - 1/2 cup prepared barbecue sauce
 - 1 (8 ounce) can sliced pineapple
 - 8 slices bacon
 
- Prepare grill for indirect cooking.
 - In a large bowl, mix together hamburger meat and barbecue sauce. Season with salt and pepper.
 - Shape mixture into 4 large patties. Place a slice of pineapple on top of each. Crisscross 2 bacon strips around each burger, and secure with toothpicks.
 - Brush oil on grate. Place burgers on grill over medium low heat. Cook, covered, until the burger is cooked through. Turn often to avoid burning the bacon.
