Chinese Teriyaki Chicken

Favorite of my daddy's. Sometimes I like to cut this chicken up and eat it like a rice bowl with some steamed veggies. It is definitely a comfort food for me and reminds me of home :)

4 lb. chicken tenders
½ c. soy sauce
½ c. brown sugar
½ c. margarine
¼ c. water
½ tsp. dry mustard

Combine in small sauce pan all but chicken. Mix well. Cook 5 minutes on medium heat. Place chicken in baking dish-meaty side down. Pour sauce over chicken. Bake 1 hour at 350 degrees. Occasionally turn chicken and brush with sauce while cooking. Serve over rice.
