Bake chicken and vegetables 50 to 55 min. or until chicken is done (165°F), and vegetables are tender and lightly browned. About 15 min. before chicken is done, bring bouillon cubes and water to boil in large saucepan; stir in rice. Cover, simmer on medium-low heat 5 min. Remove from heat. Let stand 5 min. or until rice is tender and all water is absorbed.
