This is to cook 4 skinless chicken breasts that have been marinated in harissa, olive oil and driend oregano. Directions read: Heat oven to 200 C/fan 180 C/gas 6. Put chicken in roasting poan. Cover with foil and roast for 5 minutes (yes, 5), then remove foil add cherry tomatoes and roast for 10 more mins. until tomato skins burst and chicken is cooked through. I've never cooked a chicken breast in 15 mins, but maybe I should try? They wouldn't be so dry. Seriously, though what do you think? Its a BBC recipe.
