# Method:
01 - Preheat the oven to 350°F.
02 - Heat olive oil in a large skillet over medium heat. Add chopped onion and cook for 3 to 4 minutes until softened. Stir in minced garlic and cook for 1 minute.
03 - Add sliced mushrooms and grated carrot to the skillet. Sauté for 6 to 8 minutes until mushrooms release moisture and start to brown.
04 - Stir in chopped spinach and cook until wilted. Incorporate dried oregano, dried basil, salt, and pepper. Remove from heat.
05 - Combine passata, tomato paste, sugar, and balsamic vinegar in a saucepan. Simmer over low heat for 10 minutes. Season with salt and pepper.
06 - Heat olive oil or vegan butter in a saucepan over medium heat. Whisk in flour and cook for 1 to 2 minutes. Gradually whisk in plant-based milk, avoiding lumps. Simmer until thickened, about 5 minutes. Season with nutmeg, salt, and pepper.
07 - Spread a thin layer of tomato sauce on the bottom of a 9 x 13 inch baking dish. Layer lasagna sheets, half the vegetable mixture, some tomato sauce, and a layer of béchamel. Repeat layers, finishing with lasagna sheets topped with remaining béchamel and nutritional yeast.
08 - Cover with foil and bake for 30 minutes. Remove foil and bake for an additional 15 to 20 minutes until golden and bubbling.
09 - Let rest for 10 minutes before slicing. Garnish with fresh basil if desired.
