Preheat the oven to 375F.
In a small bowl, add chicken breast, olive oil, garlic powder, cumin, Italian seasoning, salt and pepper. Mix well to combine and let the chicken marinate for at least 1 hour, refrigerated.
With a large sharp knife, carefully cut the chicken breasts lengthwise - Don't cut all the way through - creating a large pocket.
Open the chicken breasts up where you cut them and layer in the remaining ingredients.
Stick a couple of toothpicks in near the opening to keep it all together.
Heat up a large oven-safe skillet and sear the meat on both sides for about 3 minute per side.
Place the skillet in the preheated oven and finish cooking the chicken. Roast for an additional 10-12 minutes, just until chicken is cooked through.
