Well firstly you must thaw it! In my opinion the microwave is not a good idea because it will take forever and at the end you might not even have it completely thawed. I usually leave it in the fridge the night before and then leave it out for a little bit before cook it...on the counter...in a plastic baggie. Anyways before you cook it, you must wash it, not too much but just a little to ensure that some of the germs are gone. Anyways the easiest way to do chicken is to roast it in the oven. Pour some extra virgin olive oil on top, put salt, pepper, sprinkle some lemon and thyme sprigs and you should be all set to bake it at 350 for about an hour or two and you don't even have to do anything.
