You wouldn't think that lasagna could be a lean and delicious dish until you have tried this low-calorie spinach lasagna recipe. You can see from the ingredient list that it doesn't even take a whole lot of ingredients to make up this yummy dish. And the ingredients that are included are relatively lean. Instead of fatty sausage and beef, the bulk of this lasagna filling is part skim mozzarella, low-fat cottage cheese, and spinach which give the lasagna nice texture and color. There aren't too many calories coming from those ingredientsAnother great thing about this spinach lasagna is that this lasagna recipe is so easy to throw together about an hour and 15 minutes before dinner. And the majority of that time is the lasagna cooking, which frees you up to do other things. There is no need to precook the noodles. You will add water to the dish once you have layered the lasagna together, using uncooked dry noodles. Then the water will cook the noodles during baking time resulting in perfectly al dente noodles when it is finished. One less pot to wash when it is all finished is certainly worth it.
