I'm trying to eat a lot of protein lately so I bought some plain chicken fillets, however I don't know what the best method to cook it is. I've never cooked one before and I'm a self confessed cooking idiot. I always worry that I haven't cooked meat correctly so I often stay away from it! From what I understand I'd place the fillet on a baking tray, lightly cover the tray in water, but I don't know what gas mark to cook it on and for how long? Could one of you culinary geniuses please help an idiot out? Thanks.
