DH and I so rarely do a barbecue that we've only ever used the disposable ones and just done the bare basics - sausage and burgers, the odd kebab. But we want to up our game and get a proper charcoal one, and start doing more exciting meals on it that the kids can enjoy and get involved with. Any recommendations for one that's reasonably straightforward that we can learn the ropes on without it costing too much?
