Preheat the oven to 375 degrees F.
Cook the chopped onion and ground beef until the beef is fully cooked over medium-high heat in a large pan with high sides (about 10 minutes).
While the beef is cooking, cut the zucchini and summer squash into small, 1/4″ – 1/2″ cubes.
Once the beef is done cooking, set aside and drain.
Cook the zucchini and summer squash for about 7-10 minutes.
Add in the tomatoes, tomato sauce, and spices.
Continue cooking over medium heat for another 7-10 minutes, stirring often and breaking down the whole tomatoes with a spatula.
Add the cooked beef and onions back into the tomato sauce mixture and stir.
Pour about 1/4 of the tomato sauce mixture into a 9×13" casserole dish.
Place 4 of the lasagna noodles on top of the mixture, then add another 1/4 of the sauce on top of the noodles.
Add 1/2 of the cottage cheese to the casserole dish.
Top with 1/2 of the parmesan and 1/2 of the mozzarella.
Repeat steps 9-12 with the remaining ingredients.
Cover the casserole dish with foil and bake for 30 minutes.
Uncover and bake for another 15 minutes.
Let cool for a few minutes, then serve warm and enjoy!
