Legumes give us a hearty meal in this stew-like dish. Beluga lentils, a variety with small, round, black grains and a nutty taste that goes well with full-bodied sauces, are the pulse of choice here. They are simmered in a broth that is spiced up with diced chorizo and red wine. To balance the flavours, bet on the sweetness of the squash and a dollop of lemony ricotta for the perfect dish to warm up on the first cool days of autumn.
