Lemon-Onion Chicken and Gravy

The other day I got a bunch of meat on a fabulous sale.  Little by little we have been eating some and freezing the rest of the package.  One of the nights I needed something fast or we were going to end up going out to eat and I'm kind of tired of McDonald's.  So I started with a Rachel Ray cookbook again and found a recipe where she marinated slightly some chicken in lemon juice and salt and pepper.  You then used the chicken for something else, but I thought it would be good just as chicken.  This is what I came up with, the chicken was divine, the gravy only so-so, I should have added some basil or perhaps some coriander -- next time.
