Mix marinade ingredients and marinate chicken in the fridge for at least 30 minutes, or up to two hours.
While the chicken is marinating, preheat oven to 400, and prepare the veggies.
Arrange veggies on sheet pan, whisk together the olive oil, salt, and oregano and pour over the veggies - coating them all. Add freshly ground pepper to taste.
Dredge chicken in panko bread crumbs and put on sheet pan.
Bake at 400 degrees for 35-40 minutes, until internal temperature of the chicken reaches 165 degrees.
Top with 1/4 - 1/2 cup feta cheese and fresh parsley.
Enjoy!
