Beef Mince & Veggie Pie

• Meanwhile, preheat grill to high. • Slice carrot into thin half-moons. • Thinly slice celery and leek. • Thinly slice spring onion.

• In a large frying pan, heat a drizzle of olive oil over medium-high heat. • Cook carrot, leek and celery, until just tender, 3-4 minutes. • Add beef mince and cook, breaking up mince with a spoon, until just browned, 3-4 minutes.

• Add tomato paste, garlic paste and Nan's special seasoning and cook, until fragrant, 1 minute. • Stir in the water and vegetable stock powder, until slightly reduced, 1-2 minutes. Season to taste.

• Transfer filling to a baking dish and evenly spread mash potato over the top with a drizzle of olive oil. • Grill until lightly golden, 8-10 minutes. TIP: Drizzling with olive oil helps the topping to crisp and brown!
