  1. Preheat the oven to gas 6, 200˚C, fan 180˚C. Put the lentils in a large bowl with 1½ cartons of passata, the courgette, spinach and chilli flakes. Season; mix well.
  2. Spoon ⅓ of the lentil mixture into the base of a 30 x 20cm ovenproof dish. Arrange a single layer of lasagne sheets over the top, breaking in half if needed. Repeat the layers with the remaining lentil mixture and lasagne sheets twice more.
  3. Season the remaining passata and spread over the top layer of lasagne sheets. Mix the ricotta in a bowl with some black pepper and half the grated pecorino. Spoon evenly over the lasagne, then scatter over the remaining pecorino. Bake for 35 mins or until golden (cover with foil after 25 mins if it's browning too much) and the pasta is cooked through. Scatter with fresh basil and serve with salad leaves, if you like.

Tip: No time to defrost? Put the frozen spinach in a pan of boiling water and simmer for 1-2 mins. Cool under cold water; squeeze dry.
