Pasta is made from dough consisting mainly of flour and water. So essentially pasta is a other form of bread.
Lasagna is most commonly made from alternating layers of pasta, tomato sauce, veggies, cheese, and meat.
With all of that in mind, does this mean a big Mac is a lasagna? Does this also mean deep dish pizzas are lasagna?
An important part of pasta is that it’s not yeasted or leavened in any way, so anything that counts as leavened bread or cake doesn’t count.
Now, a crêpe cake, or if you were to make a sandwich using roti, or pane carasau, that’s a bit more like a lasagna.
