1. Preheat your oven to 375°F (190°C). Line a baking dish with parchment paper or lightly grease it with olive oil.
2. Using a sharp knife, carefully slice each chicken breast horizontally to create a pocket. Be cautious not to cut all the way through.
3. Season the inside of each chicken breast with salt, pepper, thyme, and garlic powder.
4. Stuff each chicken pocket with a few slices of apple and brie. Secure with toothpicks if necessary to keep the filling inside.
5. In a large skillet, heat olive oil over medium-high heat. Sear each stuffed chicken breast for 2-3 minutes on each side until golden brown.
6. Transfer the chicken to the prepared baking dish. Pour chicken broth into the dish to keep the chicken moist during baking.
7. Drizzle honey over the top of each chicken breast for added sweetness and caramelization.
8. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the internal temperature reaches 165°F (74°C).
9. Remove from the oven and let the chicken rest for a few minutes before serving. This helps the juices settle, ensuring a moist and flavorful bite.

I find that the aroma of the chicken baking is reminiscent of the times I spent in the kitchen with my abuela, learning the art of creating something special from simple ingredients.
