Preheat oven to 425℉.
Grab a standard sheet pan with sides.
If using frozen vegetarian crumbles, pour those into a sauce pan with your two containers of sauce and bring to a simmer. We are just warming up those crumbles. If you are using meat, cook ground meat in a pan first then add sauce until simmering.
In a medium sized bowl combine ricotta, cottage, and parmesan cheese. Add in eggs, spinach, and Italian seasoning. Note: it’s okay if the spinach is still fairly wet. This helps the noodles cook well. Mix until combined.
Pour ⅓ of the sauce mixture onto your sheet pan. Spread as evenly as you can. Top with 7 no cook lasagna noodles. There will be some space in between and that is okay.
Top with all the cottage cheese mixture as evenly as you can. Then, top that with ⅓ of the sauce mixture. Sprinkle 1 cup of mozzarella cheese on top. Then, add the other 7 no cook noodles, the rest of the sauce, and the rest of the cheese. Your order should be: sauce, noodles, cottage cheese mixture, sauce, mozzarella, noodles, sauce, mozzarella.
Cover loosely with foil. Make sure it’s tight around the edges but don’t pull so tight on top that all the cheese sticks to the foil.
Bake for 25 minutes. Remove foil. Bake for another 10 minutes or until bubbly. Enjoy!
