My DH does this on the bbq grill. It's a charcoal grill. He uses fresh green beans. I semi cook the bacon on one side then help him wrap the green beans bundles. We lay a sheet of the hvy duty aluminum foil on the grill then place the bundles on it. I rarely use canned anything anymore. To easy to fix the fresh. Fresh disappears faster at our house than canned. Would be easy to cook ahead of time and finish them at the campground.
