Boil 10 regular lasagna noodles until they are al dente (10-12 minutes). Place drained, dry noodles on paper towels or parchment paper.
Preheat your oven to 350 degrees.
Mix the spinach, ricotta cheese, parmesan cheese, egg, minced garlic and salt and pepper in a medium sized bowl. Combine all ingredients well.
Place a large heaping spoonful of the ricotta cheese and spinach mixture on each individual lasagna noodle and spread over the noodle evenly. Make sure each noodle has an even amount of filling.
Pour 1 cup of the pasta sauce into a 9x13 baking dish and spread over the bottom of the dish. Place each lasagna roll-up on top of the sauce seam-side down.
With a large spoon pour a heaping spoonful of the pasta sauce on top of each roll-up to cover the noodle and then sprinkle the mozarella cheese over all of the rollups. You can add extra mozarella cheese as if desired.
Cover the pan with tinfoil and bake 40 minutes. Remove the foil and bake another 5 minutes until the cheese is melted and the lasagna rollups are bubbly.
Sprinkle some fresh or dried parsley on top and they are ready to serve!
A serving is one lasagna roll-up.
