Preheat the oven to 220℃ or 210℃ fan bake. Line an oven tray with baking paper.
Cook chips
Slice the unpeeled 600 g potatoes into chips and toss on the prepared oven tray with 1 tbsp olive oil. Season with salt and pepper. Cook for 22-25 minutes, until golden and tender. Swap trays halfway through to ensure even cooking (if using).
Make toppings & salad
Combine 1 tbsp apple cider vinegar and 1 tsp honey in a small bowl with a pinch of salt. Peel and julienne 1 beetroot and toss with the vinegar and honey mixture. Set aside to marinate. In another small bowl combine 100 g hummus and ¼ cup mayonnaise with a pinch of salt. Roughly chop 1 lettuce and slice 2 tomato into wedges.
Make patties
Slice 40 g cheese. Combine 500 g lamb mince, ½ cup panko breadcrumbs, and 3 tsp barbecue seasoning in a medium-sized bowl. Season with salt and pepper. Using damp hands, combine well, then shape into patties. Push one cheese cube into each patties centre, then use damp hands to reshape the patties.
Cook patties
Heat 1 tbsp olive oil in a frypan on medium-high heat. Cook the patties, in batches if needed, for about 4 minutes on each side, until golden and cooked through. Set aside to rest.
To serve
Divide the barbecue cheese stuffed patties and chips between plates. Serve the lettuce and tomato topped with pickled beetroot on the side. Dollop over the creamy hummus.
