The best lasagna recipe ever.

The best lasagna recipe ever. A big hit in my house tonight. I found a very similar recipe that used sliced provolone instead of mozzarella so I used both. I doubled it and ended up w/ enough sauce to make 3. Instead of sweet italian sausage, I used 1 lb mild and 1 lb hot italian sausage and approx 2-1/2 lb ground beef. All else per the recipe.
