If you are planning on using chicken breasts or halves they should be cooked at 375 degrees F. for at least 45-55 minutes. The meat should not be pink and the juices should run clear. If you have meat thermometer, poultry is done when the thermometer reads 180 degrees F. Place the pineapple on top of the chicken and put them under the broiler for 3-5 minutes after the chicken is done baking. This should heat up the pineapple nicely.
Do what you can, with what you have, where you are.
