This is the mean ol' recipe that finally convinced me: I am not a fan of prosciutto. I've since been informed that this makes me weird. I would definitely make it again, though, and substitute bacon for the prosciutto. And double the caramelized onions. Mmm.
2 tsp. olive oil (or, um, bacon fat if it's right there anyway.. or if you had to dig in the fridge for it)
