Preheat oven to 220°C or 200°C fan bake. Peel and dice the potatoes into 2cm cubes. Spread in a single layer on 1-2 lined oven trays and toss with the first measure of oil and balsamic vinegar. Season with salt and pepper. Roast for 20-25 mins in the oven or until tender.
MAKE PATTIES
In a large bowl combine pork, breadcrumbs, egg, tomato sauce, ginger, and five spices and season with salt and pepper. Divide the mix into the number of burgers you're making, roll into balls and flatten into 1cm-thick patties.
COOK PATTIES
Heat the second measure of oil in a large frypan on medium heat. Cook patties for about 5 mins each side, until cooked through. Drop heat to low, brush over first measure of sweet chilli sauce and turn patties to coat.
PREP INGREDIENTS
In a small bowl, mix together the second measure of sweet chilli sauce and mayo. Toss the slaw mix together with half of the sweet chilli mayo in a large bowl. Season to taste with salt and pepper. Cut buns in half horizontally and place them back together on an oven tray. Cook buns for about 4 mins, until warm and toasted.
COOK PINEAPPLE
When the roasties have 5 mins cooking time left, add the pineapple rings to the oven tray with the roasties. Cook for 2 mins then turn and cook until roasties are finished.
TO SERVE
Fill the buns with the remaining sweet chilli mayo, slaw mix, pineapple and patties. Divide pork burgers and roasties between plates. Serve any extra slaw on the side.
