Note the difference in the last letter of the name. Lasagna is plural and refers to the noodles themselves, also plural. Lasagna is Italian American parlance and refers to the aforementioned cheesy composition, the dish in toto. A lasagna (also spelled lasagnette) is a dish of layered pasta dough that is stretched into a single shape and then baked. Often the name refers to the filling, which is generally a mixture of cheese, meat, and vegetables, and can be presented as a single, or with several layers. In American English, lasagna is generally reserved for the "layered" version, although it can also be made without the "pasta layer" in which the ingredients are placed between a loose-fitting breadcrumb-coated plastic wrapper.

Due to a large number of carbohydrates and excessive amounts of refined sugar, lasagna is rich in cholesterol, sodium, and saturated fat. It also has a lot of empty calories (that is, calories with no nutritional value).
The added fiber from the noodles will fill you up for a little while, but as a slow-digesting carbohydrate, you won’t be satiated for long. This makes you hungry again fairly quickly and for longer than if you ate the same meal plain, such as an apple or cottage cheese. Because you’ll be hungrier than you were before, you’ll probably eat more of it. To make matters worse, you’ll be eating almost a whole pizza at one sitting. No one needs to explain the dangers of overeating like that. It also causes you to retain water.
You can have as many Lasagna layers that you can think of. They can be stackable, and since the layers are soft and pliable, they can come off or stick to each other. Just add to them, right? Right.
Lasagna should be served at room temperature when the top layer has started to brown. Once that layer is browned, the layers will be crisp and melty at the same time. But there's one more benefit. The longer you wait, the more melted the sauce will be when it's served. Yummm.
Yes! In fact, top it. And the bottom layers. Turn it over. Toast it. If it's ready to eat, then make sure you've got a bottom crust that's crispy, then a gooey layer on top and then, finally, a second layer of sauce.
In American English, “tomato” is sometimes used as a plural pronoun for “tomatoes” and “pasta” is commonly spoken as a plural form of “pasta.” This is the case in the above question, where it would be more appropriate to say “does you put noodles on top of lasagna?”
Does the whole family make lasagna?
Many who make and eat lasagna are part of the extended family, usually with grandmothers and mothers in the lead. It is therefore typical for the whole family to help prepare and cook the meal. Does everyone get a slice? Most families have the tradition of serving lasagna to everyone who comes to dinner (including siblings, other relatives and friends).
