Teriyaki Chicken

This is perfect for those, "Oh crap, what am I going to make for dinner nights". I usually have all the ingredients on hand.

boneless, skinless chicken breasts
1/2c. soy sauce
1/2c. brown sugar. (I use a little less because I don't like it this sweet.)
1/4c. butter
1/2c. water
1/2tsp. dry mustard

Boil all ingredients (except chicken) for 5 minutes. Add chicken and bake in a covered casserole dish at 350 for one hour. I've also just fried the chicken until it was almost done poured the sauce over it and turned the heat down until chicken was done. Both ways are good. Serve with rice.
