A tin of beans is a store-cupboard saviour.

Toss with some pasta, garlic and a healthy glug of olive oil and you’ve got dinner. Puree with roasted veg and you’ve got the makings of a mezze platter.

Sweet potatoes or one of the hard squashes is a good match for beans. Peel, dice and roast until nicely browned.
