Vegan roasted vegetable lasagne

method:

• Preheat the oven to 200C/400F/Gas 6. Top and tail the carrots then slice them into 1/2cm-thick rings. Add them to a large baking tray, sprinkle with small pinches of salt and pepper and drizzle with a light splash of olive oil. Toss through with your hands then roast for 15 minutes.
• Meanwhile remove the stems from the red peppers and dice them. Top and tail the courgettes and peel the red onions, then slice both into 1/2cm rings. Finely chop the rosemary leaves.
• Add the red peppers, courgettes, red onion and rosemary to the baking tray with the carrots along with small pinches of salt and pepper and a light drizzle of olive oil. Toss with a spoon to combine everything together, then roast in the oven for 15 minutes.
• Drizzle a little olive oil in a medium saucepan on a medium heat. Peel and dice the garlic cloves then throw them into the saucepan and fry for two minutes. Next add the tinned tomatoes and small pinches of salt and pepper. Bring the sauce to the boil then reduce the heat and simmer for 15 minutes.
• Meanwhile add the vegan butter to a frying pan over a medium heat. Once melted, add the flour, stir to combine and fry for two minutes. Pour in the Elmlea Plant Double and whisk regularly so that the sauce becomes smooth. Gradually pour in the milk, whisking continuously so the sauce remains smooth. Season with pinches of salt and pepper, then add the nutritional yeast. Continue stirring until the sauce begins to thicken.
• To build the lasagne, first add a few large spoonfuls of the tomato sauce to a large roasting dish and spread evenly. Then layer with four sheets of lasagne, followed by a few spoonfuls of béchamel. Next, evenly spread 1/3 of the roasted vegetables on top. Repeat one more time, starting again with a few spoonfuls of tomato sauce until you have two layers of lasagne sheets. Next later with a few spoonfuls of tomato sauce, four lasagne sheets, and a few spoonfuls of béchamel. Next evenly spread the pesto over the béchamel and then layer with the remaining roasted vegetables. Finish with the last few spoonfuls of tomato sauce. Next sprinkle over the grated vegan cheese and finally spoon the remaining béchamel over the top. Spread the béchamel out evenly over the top of the lasagne.
• Roast in the oven 30-35 minutes, or until golden on top. Leave to sit for at least 10 minutes before serving.
