Lay chicken thighs on a cutting board. Using a sharp knife, butterfly the chicken thighs by slicing them almost in half lengthwise, leaving one side intact. Open the chicken thighs and lay them flat.

Drizzle the olive oil over the chicken rolls and bake for 25-30 minutes, or until the chicken is cooked through and the cheese is melted.
