Preheat the oven to 400°F. Set an oven-safe skillet nearby and pat the chicken dry with paper towels.

Place the spinach in the skillet over medium heat with a teaspoon of water. Cook for 1-2 minutes until wilted, then transfer to a towel and squeeze very dry. Chop roughly.
03 -
In a bowl, stir together the dried spinach, feta, Kalamata olives, roasted red peppers, garlic, parsley, lemon zest, lemon juice, and 1/4 teaspoon salt.
04 -
Cut a deep pocket into the thick side of each chicken breast without slicing all the way through. Season inside and outside with oregano, paprika, remaining salt, and black pepper.
05 -
Divide the filling among the chicken pockets. Secure each opening with 1-2 toothpicks so the filling stays tucked inside.
06 -
Heat the olive oil in the oven-safe skillet over medium-high heat. Sear the stuffed chicken for about 3 minutes per side until golden brown.
07 -
Transfer the skillet to the oven and bake for 15-18 minutes, until the thickest part of the chicken reaches 165°F on an instant-read thermometer.

Rest the chicken for 5 minutes. Remove toothpicks, slice if desired, and serve with lemon wedges and pan juices.
