Preheat your oven to 250C (480F). Slice chicken into bite sized strips and broccoli into bite sized pieces. Toss in a roasting tray. Drizzle with olive oil and scatter over some salt.
Cover with foil and bake for 15-20 minutes or until chicken is cooked through and the broccoli is tender.
While the chicken and broccoli is cooking smash together the sour cream and blue cheese with a fork. Or for a smoother dressing use a stick blender. Taste and add lemon juice as needed.
Serve chicken and broccoli with dressing in a bowl on the side or just slather it on top!
