Method

Preheat the oven to gas 7, 220°C, fan 200°C. Toss the vegetables with 1 tbsp olive oil per pack; then roast for 25 mins.
Reduce the oven to gas 6, 200°C, 180°C fan, and lightly oil a baking dish (23cm x 32cm). Lay 2 fresh lasagne sheets on the bottom. Top with ⅓ of the tomato sauce, ½ of the roasted veg and ½ of the lentils. Sprinkle with 25g mozzarella.
Repeat the layers, then top with the remaining lasagne sheets, sauce and cheese. Cover with foil, bake for 20 mins. Remove the foil and bake for a further 10-15 mins until the pasta is soft and sauce is bubbling. Drizzle with a little olive oil to serve.
