Prepare the chicken for cooking like you normally would. Remove any parts from the cavity, wash inside and out, pat dry, salt and pepper inside cavity if you like. We also use Luzianne Cajun Seasoning. We like onion, so I chop up an avialable onion. I then put 1/2 of the chopped onion inside the cavity along with the seasoning. Mix the ketchup and cola. Place in the pot and pour the ketchup mix over the chicken. Put the remaining onion in the pot and sprinkle your favorite seasoning over the chicken. Put lid on pot, cook on low for 8 to 12 hours depending on your busy day or night. We enjoy the sauce over rice and round out the meal with a green vegetable.
