Cheese & chilli melts
If you mix the filling ahead you can ask BBQ guests to help you cook these Mexican-style treats
Boil the sweet potatoes for 8 mins until tender, then drain. Meanwhile, heat the oil in a large ovenproof pan and cook the onion and chorizo for 5 mins until softened. Add the sweet potatoes and chickpeas and cook for 5 mins more. Roughly break the mixture up with a fork, then flatten it down lightly to form a cake. Cook for a further 8 mins, without stirring, until cooked through, crispy and golden on the bottom.
Heat grill to high. Break the eggs onto the hash, season, then place the pan under the grill and cook for 2-3 mins until the whites are set. Sprinkle with chilli to serve.
