Heat the oil in a large pan over a medium heat and fry the celery and carrots for 10 mins, stirring frequently until golden. Stir in the garlic, thyme and paprika, stir well, then tip in the tomatoes, tomato purée and stock, and bring to the boil. Tip in the penne, return to the boil, then reduce the heat and cook for 12 mins until the penne is tender. Stir in the chopped basil.

Tip the spinach into a heatproof bowl and microwave for 5 mins on high until defrosted. Meanwhile, mash the tofu with the lemon juice and nutritional yeast. Heat the oven to 200C/180C fan/gas 6.

Squeeze as much liquid as you can from the defrosted spinach, then arrange in the base of a large, shallow ovenproof dish. Spoon half the pasta mixture on top, then cover with the tofu mixture, followed by the rest of the pasta. Bake for 15-20 mins until bubbling at the edges, then scatter over the olives and remaining basil leaves. Serve half the pasta bake between two people. Cool and chill the rest to eat another day. To serve, reheat on plates in the microwave until piping hot. Will keep chilled for up to four days.
