Top with the remaining cottage cheese, then add ¼ to ½ teaspoon salt (to taste) and lots of freshly ground black pepper. Stir to combine. Now it’s lasagna assembly time! Spread ½ cup tomato sauce evenly over the bottom of a 9” by 9” baking dish. Layer 3 lasagna noodles on top (snap off their ends to fit, and/or overlap their edges as necessary). Spread half of the cottage cheese mixture evenly over the noodles. Top with ¾ cup tomato sauce, then sprinkle ½ cup shredded cheese on top. Top with 3 more noodles, followed by the remaining cottage cheese mixture (we’re skipping the tomato sauce in this layer.) Sprinkle ½ cup shredded cheese on top.
