Preheat the oven to 375 degrees.
After you have butterflied the chicken, season both sides of it with 1 teaspoon all purpose , pepper, garlic powder, onion powder, paprika, and oregano.
Place 1 tablespoon of butter under the skin of each chicken breast (this will keep the breast moist) and sprinkle the chopped garlic over the seasoned chicken
Add and arrange the potatoes, carrots, and red pepper around the chicken and sprinkle them 1/2 teaspoon all purpose (do not let it get on the already seasoned chicken)
Pour the Greek dressing over the chicken and the vegetables (shake the bottle well before doing so)
Place the chicken in the oven and allow it to bake uncovered for 1 hour and 25 minutes or until fully cooked
Every 15-20 minutes baste the pan juices over the chicken
Remove from the oven , pour some of the pan juices over the bird and allow it to sit for 5-7 minutes
Garnish with parsley (optional), serve, and enjoy!
