Cook bacon in a large non-stick frying pan over medium-high heat until crisp. Remove from heat.
Using your hands, combine bacon, beef, breadcrumbs, egg, finely chopped green onions, parsley, Worcestershire sauce and half the barbecue sauce; mix well. Shape mixture into eight rissoles (small patties.).
Heat oil in the non-stick pan over medium heat. Cook rissoles until browned on both sides and cooked through. Remove from pan, cover to keep warm.
Drain any excess oil from pan, add mustard, stock and remaining barbecue sauce; bring to the boil. Combine cornstarch and water, stir into gravy and cook until gravy thickens.
Serve rissoles with gravy, cabbage mash, and cooked greens.
