I cooked the polenta much longer until it was nice and crisp. I didn't have sherry so I used Italian Red Wine vinegar and it was still delicious. I also did not have the smoked paprika, so I'd maybe look for that as regular didn't do much for the flavor.
I've never had butter beans, they were pretty delicious. I agree there was too much broth, so I ended up using a slotted spoon. I would add top with cheese right before serving.
