it's pretty basic
i cut them in half lengthwise toss them w/ a bit of olive oil and salt and pepper and then put them in the oven at 400 degrees until the outside leaves have started to blacken. you can cook bacon while that goes on then crumble it and put it onto the roasted BS.
otherwise i cook the bacon, then put the BS into the fat to cook for about 7 minutes covered. not as good as roasting them I don't believe, but still quite tasty
