- 1 tablespoon vegetable oil
- 1 tablespoon minced garlic
- 1 tablespoon minced fresh ginger root
- 1 onion, finely chopped
- 1 pound lean ground pork
- 1 carrot, finely chopped
- 2 stalks celery, finely chopped
- 1 teaspoon soy sauce
- 1/2 cup chopped green onion
- 1/2 cup hoisin sauce
- 3/4 cup pine nuts
- 2 cups diced (1/2-inch) watermelon
- 12 iceberg lettuce leaves
- Heat the vegetable oil in a heavy, non-stick skillet over high heat. Cook and stir the garlic, ginger, and onion in the hot oil until fragrant, about 1 minute; add the ground pork to the mixture and cook until completely browned, 7 to 10 minutes. Drain any excess liquid from the skillet.
- Reduce the heat to medium. Add the carrot and celery to the pork mixture; cook and stir until the carrot and celery begin to soften, 2 to 3 minutes. Stir the soy sauce and green onions into the mixture; remove the skillet from the heat and add the hoisin sauce and pine nuts. Stir the mixture until evenly mixed. Fold the watermelon into the mixture.
- Spoon the pork mixture into the middle of the lettuce leaves; wrap the lettuce around the filling to serve.
