1 tablespoon chili powder
2 teaspoons cocoa powder
2 teaspoons dried oregano
1 teaspoon dried thyme
½ teaspoon granulated sugar
½ teaspoon salt
2 tablespoons olive oil, divided
4 boneless/skinless chicken breast halves
Preheat oven to 375˚. In a small bowl, toss together chili powder, cocoa, oregano, thyme, sugar and salt.
In a large oven-safe skillet, heat 1 1/2 tablespoons oil over medium. Brush chicken breasts with remaining oil and rub each generously with the spice mixture on both sides. Place the chicken into the skillet and sear on both sides. Place the skillet into the oven and bake until the chicken has cooked through, about 10 to 12 minutes.
