Tuscans are commonly known as
mangiafagioli, or bean eaters, and when you simmer cannellini beans on top of the stove and then finish them in the oven with a fresh tomato
ragù, you’ll understand why.
The dish is saucy and comforting—have plenty of good bread on hand—with welcome bursts of acidity from the extra tomatoes scattered on top of the casserole. Grape tomatoes tend to have a sweeter, more concentrated flavor than cherry tomatoes.
