Heat the olive oil in a large, shallow pan and add in the onions. Fry off until soft, then add in the carrot and celery, and cook down.
Add in the courgette next and cook that off for around 5 minutes until it begins to soften. Next add in the minced garlic, stir through, then scatter in the paprika and dried herbs, and stir again.
Next, add in the tomato puree and fry it off. Add in the sun-dried tomatoes and tinned cherry tomatoes, breaking them up using the spoon.
Bring to a gentle simmer, then add in the chickpeas and their liquid, and the olives. Season well with sea salt and black pepper and stir well. Pour in the Plant Based cream.
Add in the spinach next as well as the shredded basil, and stir through until the spinach begins to wilt.
Take one sheet of filo pastry at a time, scrunch tightly and place on top of the dish. Repeat this process with all of the filo pastry sheets until the top of the dish is completely covered. Sprinkle over a little water to help the sheets crisp up when baked, then evenly brush over a little olive oil and finish with a sprinkle of nigella seeds.
Place the pie into a pre-heated oven at 180 degrees Celsius for 35-40 minutes until golden, bubbling and crispy on top - enjoy!
