Set the oven at 400°F/204°C. In the interest of being quick and easy let's slice the breasts in half. Like if you were going to butterfly them but go all the way through. Lay them out in a foil lined bake pan. Then add all of the other ingredients and turn the chicken filets over a few times to get them well coated and all of the ingredients mixed together.
Put it in the oven and after 15 minutes check 'em. If they are firm to a finger poke and/or the juices are running clear they are good. Switch the oven from bake to broil for 2-3 minutes.
Then serve up your Oven Baked Lemon Chicken. Spoon some of the liquid from the pan on to the chicken. While the chicken is in the oven you could throw together a salad and put a couple of potatoes in the microwave for the carb. And, you could tear a piece of dough from the bread dough stash in the fridge and put it in the oven or the toaster oven for some homemade bread to dip in the sauce. We had a real nice well chilled California Chardonnay with ours.
Notes
You could even add some drained capers and have Chicken Piccata.
