Combine the lemon zest, lemon juice, olive oil, minced garlic, fresh thyme, oregano, and basil together in a large zip lock bag. Add the chicken breasts then seal and refrigerator for 1 hour. Remove the chicken from the refrigerator 20 minutes prior to baking.
Preheat the oven to 375 degrees. Heat an OVEN PROOF pan over medium high heat that has been coating with cooking spray. Season both sides of the chicken breasts with sea salt and freshly cracked pepper, to taste. Add the chicken breasts to the HOT pan and cook until brown, about 2-3 minutes. Flip the chicken over and place into the oven. Bake for 20 minutes then pour the remaining marinade into the pan, place back into the oven and continue baking for 5 minutes, or until chicken is cooked through. Remove from the oven and let the chicken rest for 5 minutes before slicing thinly.
While the chicken is baking. Prepare the garlic rice - click link up above for the recipe directions.
While the chicken and rice are cooking, caramelize the diced onion. Heat a sauté pan over medium low heat with 2 teaspoons of olive oil. Add the diced onion and cook, stirring occasionally, for 20 minutes. Side Note: If the pan and onion get dry either add a bit more olive oil or water and toss to coat evenly. Continue cooking until caramelized. Once the onion is caramelized, add the grape tomatoes and cook until just about to burst, about 5 minutes. Add the baby spinach then season with sea salt and freshly cracked pepper, to taste.
Place a big scoop of rice in a bowl. Add some sliced chicken along with some spinach and tomato sauté. Top with some toasted pine nuts, feta cheese, and fresh parsley. Serve with additional lemon wedges if needed. Enjoy.
