06 - Roast in the preheated oven for 40 to 50 minutes, or until the turkey reaches an internal temperature of 165°F and the vegetables are tender and golden.
07 - Remove the turkey breast from the oven and allow it to rest for 10 minutes before slicing.
08 - Slice the turkey and serve alongside the roasted vegetables. Garnish with lemon wedges and fresh herbs if desired.
