Place bacon in a large, deep skillet. Cook over medium high heat until evenly brown. Drain and set aside.
Preheat oven to 350 degrees F (175 degrees C).

20 minutes before chicken is ready, bring 3 cups water to boil in a medium saucepan. Add rice and stir. Reduce heat, cover and simmer for 20 minutes. When chicken is ready, serve over hot cooked rice.
