Preheat the oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.
In a large skillet over medium heat, sauté the onion, carrots, and bell pepper until softened, approximately 8 minutes.
Add the garlic and zucchini to the skillet, cooking for another 3 minutes, then stir in the spinach until wilted.
In a medium bowl, combine the cottage cheese, egg whites, Italian seasoning, salt, pepper, and 1/4 cup of the Parmesan cheese until smooth.
Spread 1/2 cup of marinara sauce on the bottom of the prepared baking dish.
Place a layer of chickpea noodles over the sauce, followed by 1/3 of the cottage cheese mixture, 1/3 of the vegetable mixture, and 1/2 cup of marinara.
Repeat the layers twice more, finishing with a final layer of noodles topped with the remaining marinara sauce.
Sprinkle the shredded mozzarella and the remaining 1/4 cup of Parmesan evenly over the top layer.
Cover the dish tightly with aluminum foil and bake for 25 minutes.
Remove the foil and bake for an additional 20 minutes until the cheese is bubbly and the edges are lightly browned.
Remove from oven and allow the lasagna to rest for 15 minutes to allow the structure to set before slicing.
