Pre-heat the oven to 400 degrees F.
Heat 1 tablespoon of olive oil in a large cast iron skillet on medium heat.
Mix up the spice rub of chili powder, onion powder, paprika, oregano, basil, Kosher salt and fresh ground pepper.
Coat the chicken breasts in the spice rub all over using your hands.
Then arrange the chicken breasts in the heated up skillet. Cook for 3-4 minutes on one side, then turn them over and cook for another 3. Set your oven timer for this and don't move them while they’re cooking (the flavour is developing here.)
While the chicken is searing in the pan, get a medium bowl and mix together the cooked rice, salsa, and corn kernels. Using a grater, shred the zucchini into the bowl. Mix all this goodness together with a wooden spoon till combined.
When the chicken has been seared on both sides, take the chicken breasts and place them onto a plate to rest while you do this next step.
Turn off the stove burner. Add the rice and salsa mixture to the skillet, spreading it out evenly. Then place the chicken breasts back on top of the rice.
Put the whole pan into the oven. Bake at 400F for 20-25 minutes or until an inserted meat thermometer into the chicken reads a minimum 165F. After 10 minutes, carefully take the pan out and sprinkle the feta cheese overtop.
Be careful taking the hot, heavy skillet out of the oven. Divide the chicken and rice between 4 plates. Serve warm with parsley, lime wedges and sour cream.
