Chicken en Papillote

• 8 sheets aluminum foil, each 18 inches long
• 4 tsp grapeseed oil
• 2 cups watercress leaves
• 4 boneless chicken breast halves (1 lb)
• Freshly ground black pepper
• 1 cup diced mango (about 2 mangoes)
• 8 shiitake mushroom caps
• 1/4 cup soy sauce
• 1/4 cup ketchup
• 1/4 cup red wine vinegar
• 1 tbsp grated ginger
• 2 cloves garlic, peeled and minced

1. Preheat the oven to 500F.
2. To prepare foil packets, place a sheet of foil directly on top of another; make 4 of these 2-sheet sets.
3. Smear 1 tsp grapeseed oil to the size of a chicken breast in the center of each top sheet.
4. Place 1/2 cup watercress over oil, then place a chicken breast on top of watercress.
5. Sprinkle with pepper.
6. Arrange mangoes and 2 mushroom caps on top of and around each piece of chicken.
7. Crimp the packet edges up slightly.
8. Bring soy sauce, ketchup and vinegar to a boil, then stir in ginger and garlic.
9. Remove the pan from heat and pour 1/4 sauce over each chicken breast.
10. Fold foil over each chicken breast in half and tightly crimp the edges to close the packets.
11. Heat a baking sheet in the oven 1 minute and place the 4 packets on the sheet.
12. Bake 12 minutes, then remove from oven.
13. Slit the top of the packets to serve (be careful; steam will come out), or let diners open their own packets.
