Preheat your oven to 375°F (190°C).
In a mixing bowl, combine breadcrumbs, Parmesan, basil, parsley, garlic, half of the olive oil, salt, and pepper.
Make a pocket in each Roma chicken breast by cutting a slit in the thickest part but not all the way through.
Stuff the chicken pockets with the breadcrumb mixture, sun-dried tomatoes, and mozzarella.
Secure the opening with toothpicks.
Heat the remaining olive oil in a skillet over medium heat.
Place the stuffed Roma chicken breasts in the skillet and sear for about 3 minutes on each side or until they turn golden.
Transfer the skillet to the oven and bake the Stuffed Roma chicken for 20-25 minutes or until fully cooked.
Once cooked, remove the Stuffed Roma chicken from the oven and let it rest for 5 minutes before serving.
