Combine onions and green pepper together and mix well. Add the mince, mix well. Add the coriander leaves, chutney, bread crumbs, egg, parsley, basil, basil dried leaves, and rosemary, mix well. Add salt and ground black pepper.
The mixture should be firm and hold its form while cooking, if not, add more breadcrumbs.
Separate the mixture into 8 balls, then press down to form patties. Oil a dish and place patties in the fridge to chill for 15mins.
Remove patties from the fridge. Barbeque over hot coals in a prepared grid that has been sprayed with 'Spray & Cook' or prepare a non-stick frying pan on high heat. Sprinkle the patties with olive oil, then into the pan, press down with a spatula. After 4 minutes, flip the patties.
In another pan, toast two halved rolls until lightly golden. Repeat with remaining rolls.
