Cook noodles according to package instructions or use no-boil kind.
Preheat oven to 375 degrees
In a 9x13 inch pan, spread a thin layer of marinara sauce on the pan's bottom. Not only does this prevent sticking, but it also makes it, so you don't have to use oil or spray.
Layer the noodles on top of marinara sauce on the pan's bottom, crossing over each noodle slightly to create a layer of noodles.
Now, add a thin layer of cashew basil cheese sauce, spreading evenly over the noodles.
Next, begin layering your ingredients: lentil veggie "meat," sauteed mushrooms and onions, raw spinach leaves and zucchini, and top with more marinara.
Then, repeat the layers, adding another layer of noddles and all the other layers a second time. Finally, add the sauce on top.
Now, cover tightly with aluminum foil, and place it on the center rack of the oven.
Cook for 1 hour.
Remove from oven and leave covered for 20 minutes.
Remove foil and cut it into individual pieces.
