Serve on ciabatta or pan de cristal.

I haven't made this recipe recently, and the proportions may be off. Use your judgment, rather than relying on the values given here.

The original recipe calls for blanched broccoli rabe, which I find too bitter, so I substitute it with roasted broccoli.

Ingredients Step
6 T olive oil
1 head of garlic, cloves thinly sliced
1 t. crushed red pepper flakes
Cook garlic and red pepper flakes in oil, being careful to infuse but not brown the garlic.
some of the oil
1 can white beans (½ c. from dry)
Puree the beans with the flavored oil, adding oil and water as needed.
5-6 heads (4-5 lbs.) broccoli, coarsely chopped
remainder of the oil
Toss broccoli in flavored oil, then roast in 350 degree oven until browned. Cool.
juice of 1-2 lemons
salt
pepper
Squeeze lemon juice on top of cooled broccoli, and season to taste.
8 rolls (6-8" long)
8 1-ounce slices provolone
Preheat oven to 400 degrees. Split rolls. Spread bean puree on one side. Add broccoli. Top with provolone. Toast in oven until cheese is melted, 7-10 minutes, then serve.
