Heat oil in a large deep skillet over med-high heat. Add chicken and brown on both sides until golden and almost done. Remove to a plate, sprinkle with salt and pepper and keep warm.
Pour water into skillet and add garlic. Bring to a boil and add rice and stir. Add chicken back to pan on top of rice and bring to a boil. Cover and reduce heat. Cook until liquid is absorbed and rice is tender, about 20 minutes.
