Method

Preheat the oven to gas 4, 180°C, fan 160°C. Blitz the red onion and carrot in a food processor until finely chopped, then add the garlic and peppers and blend again to a rough paste. Add the passata, 100ml water and the oil; blend again to combine, then season. Transfer to a large bowl and stir in the lentils and olives.
Cover the bottom of a 25 x 30cm baking dish with about a quarter of the sauce, then cover with a layer of pasta (a third of the pasta). Cover the pasta with another quarter of the sauce, a quarter of the oat spread, a quarter of the cheese-alternative and another layer of pasta. Repeat with another layer. Finish with the remaining sauce, oat spread and cheese-alternative.
Bake in the centre of the oven for 40 mins until the pasta is tender to the point of a knife. Rest for 10 mins, then scatter over the basil leaves to serve.

Cook's tip: For a lighter version, leave out the grated cheese-alternative.
