Mushroom Gravy over Baked Chicken with Brown Rice

I used olive oil to cook down the mushrooms then added whole wheat flour. Once that thickened I poured in the milk, seasoned with salt and pepper, reduced to simmer and voila... gravy. I put some chicken tenders in a small baking dish and covered with the gravy and baked at 400 for about 30 minutes. I put all that over some long grain brown rice... yum.
