A thick Tuscan soup of white beans, kale, and stale bread that gets even better after a night in the fridge.
Taste before adding salt: canned beans, stock, and the parmesan rind all bring their own saltiness, so season at the end. The soup looks thin right after simmering; that’s normal, it thickens once the bread has had time to rest in it, so resist the urge to add extra bread to compensate. A parmesan rind is worth saving in the freezer specifically for soups like this one.
