Cook the lasagna as instructed on the box. When done, drain the pasta and rinse with warm water. Then, spread out the lasagna noodles onto parchment paper so they are ready for the filling.

While cooking the lasagna, cook the Italian Sausage in a stovetop pan until browned. When done, drain away all grease and add to a large bowl for mixing.

Heat a tbsp of olive oil in a pan and then slightly cook the prepared strips of spinach. This should only take a couple of minutes.

Add the spinach, ricotta, mozzarella, garlic, italian seasoning and pepper to the bowl with the sausage and stir until well combined.

Add a spoonful of mixture to each noodle. Leave a little room at top to start the fold over process. The mixture will probably only take up about 4 inches on each noodle. You can always go back and add more if there is some left in the bowl!

Roll up each noodle. (if freezing, read the directions below BEFORE moving ahead.)

Add a little marinara sauce to the bottom of the baking dish, add the noodles, and then top with a little more sauce and some mozzarella cheese!

Bake covered at 350 for 40 minutes. Then, remove the cover and bake for 5 minutes more.
