Wash the chickens, pat dry , rub the chicken, inside out with olive oil and lemon juice mix to make it smell nice and fresh. Also rub the chicken with the same mix of spices that will be added to the ground beef and rice mix. You can use any stuffing variations you like, such as plain vegetables with or without rice, wheat, spiced up rice, no meat or whatever you feel like. there is no set ingredients, you can use creativity and come up with something new and delicious. Saute' the ground beef with small chopped onions, add spices, black pepper, all spice, cardamom and salt to taste. Wash the rice, soak for about 15 minutes in warm water, drain from the water and add to the meat when it is done cooking. You may add a little bit of cooking oil at this point so the rice does not become sticky . cook the rice half way, remember, it is going to continue cooking once its inside the chicken and baking. Stuff the chicken with the cooled rice and beef mix, wrap the chickens with aluminum foil really well, put in the baking pan and cook in the oven for about 2.5-3 hours on 450 degrees F. depending on the number of your chickens and their size . make sure to add water to the pan to keep the chicken moist. You may stuff it also with pre-cooked "Freekeh" which is roasted wheat, found in middle eastern stores in the states. Unwrap your master piece...ENJOY!!
