2 medium oranges, cut in half
8 tablespoons extra virgin olive oil, divided
2 tablespoons Silan date honey
3 teaspoons sweet paprika

Preheat oven to 375°F.
Line a large baking dish with parchment paper. Place chicken breast side in the center of the dish. Lightly squeeze some juice over the chicken.
Place two orange halves in the cavity of the chicken. Place two orange halves on either side of the chicken.
