# Method:

01 - Preheat the oven to 400°F.
02 - Heat olive oil in a large ovenproof deep skillet over medium heat. Add onion and garlic, sauté for 2 minutes until fragrant.
03 - Add carrot, red pepper, mushrooms, and zucchini. Cook for 5-6 minutes until softened and beginning to brown.
04 - Stir in smoked paprika, oregano, thyme, chili flakes, and tomato paste. Cook for 1 minute to bloom the spices.
05 - Add canned tomatoes, soy sauce, red lentils, and vegetable stock. Bring to a simmer, cover, and cook for 15-20 minutes until lentils are tender and sauce has thickened. Season with salt and pepper.
06 - Melt butter in a medium saucepan over medium heat. Whisk in flour and cook for 1 minute. Gradually whisk in milk, stirring constantly until thickened, about 5 minutes. Remove from heat and stir in nutmeg, cheese, salt, and white pepper.
07 - Remove half the vegetable lentil mixture from the pan and set aside. Layer one-third of the béchamel over the remaining sauce in the pan, then arrange lasagne sheets on top, breaking to fit as needed.
08 - Spread half the reserved lentil mixture over the pasta, pour another third of béchamel, and add another layer of lasagne sheets.
09 - Top with remaining lentil mixture, final layer of lasagne sheets, and remaining béchamel. Sprinkle with grated mozzarella.
10 - Cover pan loosely with foil and bake for 25 minutes.
11 - Remove foil and bake for another 10-15 minutes until golden brown and bubbling. Let stand for 10 minutes before serving. Garnish with fresh basil if desired.
