For the pickled beets:
1. Position a rack in the center of the oven & preheat the oven to 425ºF. Place the chicken on a cutting board and pat dry using paper towels. Season the inside of the cavity with ½ teaspoon of salt. Place the lemon halves, garlic head, and herbs inside the cavity. Place the chicken breast-side up in a large cast-iron skillet or an oven-safe frying pan. Sprinkle the chicken with the remaining 1 ½ teaspoon of salt all over.
