Step 1

Combine the mince, onion, garlic, egg, herbs, breadcrumbs and barbecue sauce in a bowl. Shape into 4 patties. Heat a non-stick frying pan over medium-high heat. Cook patties, turning occasionally, for 8-10 mins or until cooked through. Transfer to a plate. Cover with foil to keep warm.

Step 2

Cook the bacon in the frying pan over medium-high heat for 4-5 mins or until crispy. Push to one side. Add the pineapple rings and balsamic and cook for 2-3 mins or until golden.

Step 3

Top roll bases with lettuce, patties, extra barbecue sauce, bacon, tomato, pineapple, parsley, red onion and remaining roll.
