Preheat oven or air fryer to 190℃-375℉. If using an oven, line a baking tray with parchment paper.
Place the potatoes in a mixing bowl. Add the olive oil and all the seasonings, mixing to combine.
Place the seasoned potatoes on the lined baking tray and bake for 25 to 30 minutes, mixing halfway through, until soft and golden. Remove and let cool. If using an air fryer, cook for 18-25 minutes.
Place a large rimmed pan over high heat, and add olive oil and the beef mince. Sear for 6-7 minutes. Add the garlic, spring onions (scallion), ground cumin, Italian herbs, and seasoning to taste. Mix to combine and cook for 1 to 1 ½ minutes.
Add crushed or diced tomatoes and tomato passata, mix well, reduce heat to low, and simmer for 15-20 minutes, stirring occasionally. Remove from the stovetop.
Evenly divide the potatoes into 5x 750ml meal prep containers. Add mozzarella cheese and beef mince over the top. Garnish with sour cream, spring onion (scallion), and Sriracha mayonnaise. Dig in.
