A simple dish of creamy, thin-skinned beans and broth on toast is easy to make, and a comfort to eat alone or feed a crowd. If you make the beans ahead of time, they can keep in the fridge for 3 days, but may need a splash of water added when you heat them up. The broth is a great way to make use of parmigiano rinds, if you happen to be saving those, but if you don’t have any lying around, you can still make it rich with umami: Whisk a heaped tablespoon of white miso with a little of the bean broth to make it smooth and lump-free, then add it back to the pot. It will add a similar, savory depth. The dish seems plain, but it won’t be if you season the broth well, and garnish each bowl generously with olive oil, grated cheese and herbs, just before you eat it.
