Preheat oven to 400°F (200°C).
In a small bowl, mash the crushed peaches into the honey.
In another bowl, combine the salt, black pepper, cayenne, crushed red pepper, garlic, and oregano.
Rub the spice mixture generously over the turkey breast.
Drizzle the peach and honey mixture over the seasoned turkey.
Place the turkey in a roasting pan. Add water and butter to the bottom of the pan.
Roast at 400°F (200°C) for 25 minutes, or until a golden crust forms.
Reduce the oven temperature to 325°F (160°C) and continue roasting for approximately 1 hour, or until the turkey is cooked throughout and reaches the proper internal temperature.
Baste the turkey periodically throughout the cooking process.
