• Preheat oven to 240°C/220°C fan-forced. Cut sweet potato into fries. • Place fries on a lined oven tray. Drizzle with olive oil, season with salt and toss to coat. Bake until tender, 20-25 minutes. • In the last 5 minutes, sprinkle Parmesan cheese over fries, then bake until golden and crispy, 5 minutes. TIP: If your oven tray is crowded, divide the fries between two trays.

• While fries are baking, in a medium bowl, combine beef mince, garlic paste, fine breadcrumbs, Nan's special seasoning and the egg. Season with salt and pepper. • Shape beef mixture into 2cm-thick patties (1 per person) slightly larger than your buns. Transfer to a plate. • When fries have 15 minutes remaining, heat a large frying pan over medium-high heat with a drizzle of olive oil. When oil is hot, cook patties until just cooked through, 4-5 minutes each side.

• Meanwhile, slice avocado in half, scoop out flesh and thinly slice. Set aside. • In a second medium bowl, combine a drizzle of olive oil and vinegar. Season, then add mixed salad leaves. Toss to coat. • Halve bake-at-home burger buns, then bake directly on a wire oven rack, until heated through, 2-3 minutes.

• Spread bun bases with mayonnaise. • Top with a beef patty, salad and avocado. • Serve with sweet potato Parmesan fries. Enjoy!
