Place chicken in a 9x13 inch baking dish. Pour melted margarine over the chicken strips. Season with salt and pepper, and sprinkle with dry onion soup mix.
Pour 3/4 of a cup of water into the bottom of the pan, helping the chicken stay moist.
At 30 minutes, turn the chicken and pepper the bottom of the chicken.
Bake 40 minutes in the preheated oven, or until chicken is no longer pink and juices run clear.
