Preheat the oven to 400F. Get out a 9’’ X 13’’ baking dish.
Add some tomato sauce at the base of the baking dish, layer with lentil noodles, add a little more tomato sauce and use a silicone brush to even out sauce. Add zucchini slices, top with mushrooms, and then add spinach.
Top with your cheese blend, and then cover with tomato sauce, layer with lentil noodles and repeat, adding sauce, zucchini, mushroom spinach, cheese, sauce and noodles.
Top the last layer of noodles with sauce and cheese. Bake for 40 minutes on a baking tray, in case anything spills out. Enjoy!
