NZ All-American Veggie Mince & Caramelised Onion Pie

• In a large frying pan, heat a drizzle of olive oil over medium-high heat. • Cook onion, stirring, until softened, 5-6 minutes. • Reduce heat to medium. Add the balsamic vinegar, brown sugar and a splash of water and mix well. Cook until dark and sticky, 3-5 minutes. Transfer to a small bowl.

• Return the frying pan to medium-high heat with a drizzle of olive oil. Cook leek and carrot until tender, 3-4 minutes. • Add plant-based mince and cook, breaking up with a spoon, until just browned, 4-5 minutes.

• Add All-American spice blend (see ingredients), tomato paste and garlic paste and cook, stirring, until fragrant, 1-2 minutes. • Add the water and cook until slightly thickened, 1-2 minutes. • Remove pan from heat and stir through baby spinach leaves and caramelised onion.

If you've added shredded Cheddar cheese, sprinkle over the pie filling before topping with filo pastry.
