Step 1

Add the cottage cheese to a blender or food processor and blend until smooth. Set aside until needed.

Step 2

Heat a large skillet (I used 10 inch) over medium heat and add the olive oil and onion. Cook onion for 2 minutes and then add in the green pepper and garlic. Cook another 4-5 minutes and then add in the tomato sauce, diced tomatoes, pasta and water.

Step 3

Stir until everything is mixed evenly and then cover and let simmer for about 30 minutes, until noodles are cooked through. You will need to stir lasagna a few times to make sure that the pasta cooks evenly. This is especially important if using actual lasagna noodles because they have a tendency to stick together more.

Step 4

Once pasta is cooked through, remove the lid and stir in the spinach and 3/4 cup of the mozzarella cheese. Next, top with the remaining 1/4 cup cheese and then spoon the blended cottage cheese over the top. Cover again and let cook for another 5 minutes, or until cheese is melted.
