Preheat the oven to gas 7, 220°C, fan 200°C. Put the chicken drumsticks into a bowl and coat them in the BBQ sauce. Put onto a lined baking tray and season. Roast in for 45 mins, basting with the sauce halfway through cooking. Meanwhile, mix the couscous with the mango then serve on top of lettuce and serve with the roasted chicken.
