Rub it with olive oil before you put it in the oven. However I have found that tastiness often depends on the chicken - cheaper ones from the supermarket often taste less good that ones which have led a better life. M&S sell one of the best ones IMO.
Put between 2 sheets of grease proof paper or wrap loosely in cling film and roll out with a rolling pin until you have escalops that are approx 1cm thick. Stuff with cheese (preferably Wensleydale with Cranberries and roll up, tucking the edges in to seal. Dip in egg and roll in breadcrumbs, and place into a heated frying pan with a spot of oil. Brown all over and transfer to oven-proof dish. Voila... homemade chicken kievs !
For roast chicken... rub half a lemon all over the chicken, sprinkle with coarsely ground black pepper and stuff with a big bunch of fresh thyme and roast in the oven.
Put half a lemon inside. Cut a whole bulb of garlic in half and put it around the chicken.
I`ve just had what I call my summer roast when I don`t want the full works. I rub olive oil over the chicken, then roast it in cajun spices with lemon, garlic and thyme. I had it with roasted med vegetables and crushed baby new potatos.
