Heat a large pot of water. Add 1 tsp salt and bring to a boil.
Heat the oven to 200C.
Brush a baking dish for lasagna with olive oil. Set aside.
Add about 6 thick large cabbage leaves to the boiling water. Steam them until they start to soften, then drain on a paper towel.
To prepare the Bechamel:
Heat a medium pot on medium heat. Add olive oil. When hot, add the flour and whisk until combined.
When combined, add the milk, stirring continuously. Cook until thick.
Add the nutmeg, salt, and pepper. Set aside.
In a large skillet heat some olive oil. Add onion and garlic and saute until golden.
Add the textured soy protein granules and the tomato sauce. Stir to combine for about 2 minutes.
Add the rest of the ingredients and turn off the heat. Set aside.
To assemble the lasagna, add ¼ of the marinara mixture to the bottom of the prepared dish.
Cover with 2 large soft cabbage leaves. Repeat with the rest of the ingredients.
Pour the Bechamel over the layers, sprinkle with shredded cheese and bake until lightly golden on top.
Top with fresh chives and serve.
