Prepare the sauce: Heat olive oil in a heavy saucepan over medium heat. Cook garlic until fragrant, then add chopped tomatoes and season with salt and pepper. Simmer for 15 minutes.
Cook manicotti shells according to package directions. Drain and place in cold water.
Prepare the filling: In a mixing bowl, combine ricotta, cooked spinach, Parmesan, and mozzarella. Season with salt and pepper.
Spoon a small amount of sauce into the bottom of a baking pan. Fill each manicotti shell with the ricotta mixture and place in the pan.
Pour remaining sauce over the filled shells and sprinkle with additional Parmesan cheese.
Cover the pan and bake at 375°F (190°C) for 20 minutes. Remove cover and bake for an additional 20 minutes until cheese is browned.
Let rest before serving. Enjoy!
