Marks and Spencer are professionals at making our mouths water at the sight of delicious new items in its food hall, and its summer food range is no exception. Now that it’s well and truly picnic season (thanks summer for finally showing up), shoppers can count on M&S to supply all the tastiest picnic nibbles. Not only has M&S created pre-made picnic hampers to take the faff out of sorting food, but it has also introduced an epic foot-long sausage roll.
