In a large plastic bag or mixing bowl toss the drumsticks in half the taco seasoning. Set it aside for now.
Heat a large skillet to medium heat and add 1 tablespoon olive oil. Once it's hot, pour in your chicken and sear until lightly browned (approximately 2 minutes on each side)
Remove the drumsticks from the pan and set them aside on a plate for now. Add the can of undrained can of tomatoes with green chilies, water and remaining taco seasoning into the pan and bring to a simmer.
Add rice and stir well. Place drumsticks on top of the rice, cover pan with lid, and reduce heat to low. Cook 20 minutes until all water is absorbed and chicken has reached 165 degrees F.
