Preheat your oven to 375°F (190°C). Lightly grease a baking dish with olive oil or a non-stick spray and set it aside.

In a medium skillet, warm 1 tablespoon of olive oil over medium heat. Add the chopped spinach and sauté for about 2 to 3 minutes, just until wilted. Remove from heat and allow it to cool slightly.
03 -
In a mixing bowl, combine the cooked spinach with ricotta, mozzarella, Parmesan, minced garlic, oregano, salt, and pepper. Stir until it forms a thick, creamy mixture.

Using a sharp knife, carefully cut a pocket into the thickest side of each chicken breast. Be gentle and avoid slicing all the way through.
05 -
Stuff each chicken breast with the spinach and cheese mixture. Secure the openings with toothpicks or kitchen twine to keep the filling inside during cooking.
06 -
In a large skillet, heat the remaining tablespoon of olive oil over medium-high heat. Place the stuffed chicken breasts in the pan and sear them for about 2 to 3 minutes per side until they develop a golden crust.
07 -
Transfer the seared chicken to your prepared baking dish and bake for 20 to 25 minutes, or until the internal temperature reaches 165°F (75°C) and the filling is hot and bubbly.

Let the chicken rest for 5 minutes before serving. Optionally, drizzle with fresh lemon juice for added brightness.
