Preheat oven to 375°F (190°C).

In a small bowl, mix salt, pepper, onion powder, garlic powder, and paprika. Drizzle 2 tablespoons olive oil over chicken and rub with seasoning mixture.

Combine filling ingredients in a bowl and set aside.

Cut a wide pocket in each chicken breast. Do not cut all the way through.

Stuff each chicken breast with the prepared filling.

Heat 2 tablespoons olive oil in a large oven-safe skillet over medium-high heat. Sear each side of stuffed chicken for 2–3 minutes until browned.

Transfer skillet to oven and bake 25–35 minutes, or until chicken is fully cooked (internal temp of 165°F).

Let rest 5 minutes before serving.
