500 grams coarse textured Italian sausages
1 tablespoon olive oil
4 hamburger buns, halved
1 clove garlic, peeled
1-2 tomatoes, sliced
Red onion jam
3 tablespoons olive oil
3 red onions, thinly sliced
2 cloves garlic, crushed
¼ cup brown sugar
½ cup balsamic vinegar
sea salt and freshly ground pepper
Red onion jam: Heat the oil in a medium sauté pan. Add the onions with a good pinch of salt, cover and cook for 10 minutes, stirring occasionally. Add the sugar and garlic and cook for 1 minute. Add the vinegar and bring to the boil. Reduce the heat and simmer uncovered, stirring occasionally, for 10 minutes or until most of the liquid has evaporated and the onions are glossy.
Burgers: Remove the skin from the sausages and discard. Form the meat into 4 patties the same size as the buns. Heat a sauté pan over medium heat and cook the patties until golden on both sides and fully cooked through. Drain on kitchen towels.
Toast the buns and rub the cut sides with the clove of garlic. Spread with mayonnaise and salad, a pattie, slices of tomato and a spoonful of red onion jam. Serve with oven roasted fries if desired.
