1 tsp. olive oil 

1 1/2 C. sliced onion 

1 T. minced garlic 

1 green bell pepper, thinly sliced 

1 yellow bell pepper, thinly sliced 

10 whole nicoise olives or 5 pitted black olives, chopped 

1/4 tsp. fennel seeds 

1/8 tsp. dried rosemary 

1/8 tsp. dried thyme 

pinch of red pepper flakes 

1 1/4 pounds boneless, skinless chicken thighs 

2 tsp. red wine vinegar 

1/8 tsp. ground black pepper 

 

Preheat the oven to 425°F. In a large, nonstick skillet, heat the oil over medium heat. Add the onion and garlic. Cook, stirring frequently, for 4 to 5 minutes, or until the onion is translucent. Add the bell peppers. Cook, stirring frequently, for 5 to 6 minutes, or until softened. Add the olives, fennel, rosemary, thyme, and red pepper flakes. Cook, stirring, for 1 minute longer. Place the chicken in a shallow baking dish and arrange in a single layer. Drizzle with the vinegar and sprinkle with the black pepper. Spoon the vegetable mixture over the chicken. Bake for 25 to 30 minutes, or until the chicken is no longer pink in the center and the juices run clear.
