Mix olive oil, lemon juice, cumin, paprika powder, ginger, turmeric, garlic, pepper (or chilli), and half of the coriander to form a paste.
Cut turkey breast into 4 or 8 pieces. Rub the paste over each piece. Refrigerate for 3 to 4 hours.
Preheat oven to 160°C (320°F).
Transfer the marinated turkey to a baking dish. Add tomato pieces, olives, and chicken broth. Bake for about 1 hour, until the turkey is cooked through (internal temperature 74°C / 165°F).
Top with remaining coriander and serve with flatbread.
