Host a bank holiday barbecue for 12 for under £25

With a bank holiday upon us and warmer weather promised, we can leave the jumpers indoors, hoist the barbecue out of the shed and enjoy the sunshine. But fear of a bank-breaking grocery bill needn’t curtail your weekend plans; with some savvy planning and not too much effort, you can put on a fabulous party spread for 12, including the extras (but, sadly, not the booze), while staying south of £25.
