Rinse the chicken and pat dry. On a cutting board, firmly push down on the chicken breast with the palm of your hand. Using a sharp knife in your other hand, fillet the breast by cutting into the breast with the knife moving horizontally through breast. Once filleted, cut in half.
Add chicken to a large bowl and add the marinade. Mix to ensure all chicken is coated. Marinate for 4-6 hours in the refrigerator.
After chicken has been marinated, add 3 tablespoons ghee to a large skillet and heat over medium-high. Once the ghee is hot, add the chicken pieces to the pan. Cook about 5-7 minutes until the underside has turned white and it is almost cooked through. Chicken should be browning on the underside. Turn over to continue cooking until chicken has cooked through. Remove from pan and continue cooking until all the chicken is cooked.
While the chicken is cooking, melt 2 Tbsp of ghee in a medium skillet. Once the fat is hot, add the green beans, lemon pepper, garlic sea salt, and juice of 1 lemon.
In a small sauce pan, add the remaining 1 Tbsp. of ghee and heat to just over medium heat. Add the cherry tomatoes and cook for about 5-8 minutes, allowing them to cook through and blister on the outside.
Add chicken and green beans to plate, top with a few blistered cherry tomatoes and sprinkle with parsley and sea salt and pepper (to taste).
