1. Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius). Line a nine- x 13-inch (23- x 33-centimeter) baking pan with Gefen Parchment Paper.
2. Place sweet potatoes on the bottom of the pan. Sprinkle rice all over. Add pastrami pieces and then the chicken pieces. Spread onion over all. Do not mix. Drizzle the diluted apricot jam over all.
3. Combine the water, olive oil, salt and pepper, vinegar, onion soup mix, and slightly defrosted herbs in a small bowl. Mix well. Pour evenly over the entire pan.
4. Cover the pan with parchment paper and then tightly with aluminum foil. Bake for one and a half hours. Remove from oven and let sit at least five minutes before serving.
