Indian Chicken, Lentil & Veggie Curry Pie

• In a large frying pan over medium-high heat with a drizzle of olive oil. Cut chicken breast into 2cm chunks. When oil is hot, cook chicken, tossing occasionally, until browned and cooked through, 5-6 minutes. Transfer to a bowl. • Return frying pan to medium-high heat with a drizzle of olive oil. Cook leek and carrot until softened, 4-5 minutes • Add plant-based butter, garlic paste, Mumbai spice blend, mild North Indian spice blend and tomato paste and cook until fragrant, 2 minutes. • Add lentils, vegetable stock powder, coconut milk, the water and brown sugar. • Bring to a simmer, then cover with a lid and cook, stirring occasionally, until the lentils are soft, 20-22 minutes. • Season with pepper to taste. Stir through chicken and baby kale until wilted.

• While the lentils are cooking, cook potato in the boiling water, over high heat, until easily pierced with a fork, 10-15 minutes. Drain and return potato to the saucepan. • Add plant-based milk and a generous drizzle of olive oil. Season with salt and pepper, then mash until smooth. Cover to keep warm.

• Preheat grill to high. Transfer lentil filling to a baking dish, then top with potato mash. • Run a fork over mash to create an uneven surface. Sprinkle with brown mustard seeds and drizzle with olive oil.

• Grill pie until lightly browned, 10-15 minutes.
