In a small bowl, combine the Ras el Hanout, Harissa, and turmeric powder to make your Moroccan spice blend. Divide in half.
Mix olive oil, lemon juice, 1/2 of lemon zest, 1/2 of the Moroccan spices and salt and pepper to taste. Pour over chicken in a pan, bowl or resealable plastic bag.
Marinate chicken in refrigerator for 1 to 2 hours—longer if the chicken has skin. (If chicken has skin, loosen skin from meat to allow marinade to penetrate meat under skin.)
Preheat oven to 450F. Mix cut-up vegetables with olive oil, remaining Moroccan spices, remaining lemon zest, salt and pepper. Roast vegetables for 20-30 minutes.
If rehydrating freeze-dried peas and tomato flakes (or any other dehydrated veggies), soak in warm to hot chicken (or vegetable) broth for 10 minutes.
Mix all vegetables in one pan. Keep warm in oven until chicken and couscous is cooked.
Grill chicken for approximately 20 minutes (turning once) or until done.
Spread couscous across bottom of a pan or serving bowl. Pour hot broth over couscous, mix and allow to set 7 to 10 minutes until couscous has absorbed all liquid and is semi-dry and al dente.
To serve place couscous on plate, top with mixed vegetables, chopped cilantro or parsley and almonds.
