In a big pot, combine the beans with aromatics, Parmesan rinds, rosemary, and thyme. Add water to cover by about 2 inches. Bring to a boil, then reduce the heat to low and simmer. Discard aromatics, Parm rinds, and herb sticks.
Salt the beans to taste and add black pepper.
In a saute pan, sweat the leeks and green garlic in olive oil and salt until melty-like.
Blitz the parsley, lemon zest, salt, black pepper, and olive oil in a food processor. Alternatively, chop and whisk together with olive oil.
Warm the beans, then stir in the melted leeks and green garlic with the pistou.
Serve with crusty bread and a green salad dressed with lemon-juice vinaigrette. Enjoy with Verdicchio or Nebbiolo.
