Pre-heat oven to 350°F.
Bring a medium pot of water to a boil. Once the water starts to boil, immerse the bag of shredded duck in the water and boil for 8 minutes, uncovered.
Remove the bag from the water and open using scissors. Transfer the shredded meat to an ovenproof dish lined with paper towel.
Toss the shredded duck meat a little and then cover with a paper towel. Press down on the duck meat to absorb some of the excess grease and then remove the paper towel from the dish.
Add the remaining ingredients to the dish with the duck, and season with pepper to taste.
Mix all ingredients and transfer to the oven. Cook for 25 minutes or until the edges start to bubble.
Remove from the oven and serve immediately with toasted pita wedges and crudités.
