Method
Step 1
Preheat the oven to 200°C. Prepare all ingredients as indicated above.
Step 2
Place the potato chips onto a tin foil lined tray. Sprinkle with the rosemary and season with salt and pepper. Drizzle with a generous amount of olive oil and mix. Roast them in the oven for 25-30 minutes.
Step 3
Season the steak mince generously with salt and pepper. Divide the mince into 2 patties per person. Place the cheese on top of the one patty and then sandwich the cheese with the other patty on top, so that the patty has a cheese middle. Set aside on a plate in the fridge.
Step 4
Place a small pan with a little olive oil on medium-high heat. Add the tomatoes and a pinch of salt, and cook for 3 minutes. Add the garlic and tomato paste and cook for another minute. Then mix in the balsamic vinegar, sugar and water and cook for 3-4 minutes until the relish has thickened.
Step 5
Place a pan on a medium-high heat with a little olive oil. When hot, fry the burger patties for 4-6 minutes per side. Remove and set aside.
Step 6
Brown the rolls cut-side down in the same pan.
Step 7
To assemble, place a lettuce leaf on the bun, with the patty on top. Add a dollop of tomato relish and a few slices of red onion. Serve with the rosemary fries and Sriracha Mayonnaise.
